The driver includes three on-board 150 µF capacitors, which might be sufficient for brief tests and limited low-power operation, but adding a bigger capacitor is strongly recommended for most applications.\u003c\/p\u003e\n\u003cp\u003eThe logic connections are designed to interface with 1.8 V to 5 V systems (5.5 V max).

Note that the current limiting threshold is not highly precise (we have seen some units limit the current as low as about 50 A when the threshold is set to the board’s default of 60 A), and it is less accurate at especially low settings (indicated by the dashed portion of the curve).\u003c\/p\u003e\n\u003ctable class=\"picture_with_caption center wide\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cimg class=\"wide\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/0J7120_600.png\" alt=\"\" data-gallery-pictures='\u0026lt;{\"id\":\"0J7120\",\"caption\":\"\\u003cp\\u003eCurrent limit vs. VREF resistor for the Pololu G2 High-Power Motor Driver 18v25.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J7120.98x98.jpg?f7523946ce2bd9b2f90a02ad264f81df\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J7120.600x480.jpg?f7523946ce2bd9b2f90a02ad264f81df\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J7120.1200.png?f7523946ce2bd9b2f90a02ad264f81df\",\"longest_side\":600}\u0026gt;' data-picture-id=\"0J7120\" data-picture-longest_side=\"600\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFault conditions\u003c\/h3\u003e\n\u003cp\u003eThe motor driver can detect several fault states that it reports by driving the \u003cspan class=\"overline\"\u003eFLT\u003c\/span\u003e pin low; this is an open-drain output that should be pulled up to your system’s logic voltage.

The H-bridge is made up of one N-channel MOSFET per leg; the rest of the board contains the circuitry to take user inputs and control the MOSFETs. The absolute maximum voltage for this motor driver is 40 V, and higher voltages can permanently destroy the motor driver. Under normal operating conditions, ripple voltage on the supply line can raise the maximum voltage to more than the average or intended voltage, so a safe maximum voltage is approximately 34 V.\u003c\/p\u003e\n\u003cp\u003eThe versatility of this driver makes it suitable for a large range of currents and voltages: it can deliver up to 13 A of continuous current with a board size of only 1.3? × 0.8? and no required heat sink. The module offers a simple interface that requires as few as two I\/O lines while still allowing for your choice of sign-magnitude or locked-antiphase operation. A current sense output gives an indicator of motor current, and the driver can limit the motor current to a configurable threshold. The power supply inputs feature reverse-voltage protection, while integrated detection of various fault conditions helps protect against other common causes of catastrophic failure; however, please note that the board does not include over-temperature protection.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating voltage: 6.5 V to 40 V (absolute maximum)\u003c\/li\u003e\n\u003cli\u003eOutput current: 13 A continuous\u003c\/li\u003e\n\u003cli\u003eInputs compatible with 1.8 V, 3.3 V, and 5 V logic\u003c\/li\u003e\n\u003cli\u003ePWM operation up to 100 kHz\u003c\/li\u003e\n\u003cli\u003eCurrent sense output proportional to motor current (approx. 40 mV\/A; only active while H-bridge is driving)\u003c\/li\u003e\n\u003cli\u003eActive current limiting (chopping) with default threshold of 30 A (can be adjusted lower)\u003c\/li\u003e\n\u003cli\u003eReverse-voltage protection\u003c\/li\u003e\n\u003cli\u003eUndervoltage shutdown\u003c\/li\u003e\n\u003cli\u003eShort circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eGeneral specifications\u003c\/h2\u003e\n\u003ctable class=\"specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMotor channels:\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMinimum operating voltage:\u003c\/th\u003e\n\u003ctd\u003e6.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMaximum operating voltage:\u003c\/th\u003e\n\u003ctd\u003e40 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eContinuous output current per channel:\u003c\/th\u003e\n\u003ctd\u003e13 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eCurrent sense:\u003c\/th\u003e\n\u003ctd\u003e0.04 V\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMaximum PWM frequency:\u003c\/th\u003e\n\u003ctd\u003e100 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMinimum logic voltage:\u003c\/th\u003e\n\u003ctd\u003e1.8 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMaximum logic voltage:\u003c\/th\u003e\n\u003ctd\u003e5.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eReverse voltage protection?:\u003c\/th\u003e\n\u003ctd\u003eY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eDimensions\u003c\/h2\u003e\n\u003ctable class=\"specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eSize:\u003c\/th\u003e\n\u003ctd\u003e1.3? × 0.8?\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eWeight:\u003c\/th\u003e\n\u003ctd\u003e3.3 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eUsing the motor driver\u003c\/h2\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cp\u003eThe motor and motor power connections are on one side of the board, and the control connections (1.8 V to 5 V logic) are on the other side.

There are two options for making the high-power connections (VIN, OUTA, OUTB, GND): large holes spaced 5 mm apart, which are compatible with the included terminal blocks, and pairs of 0.1?-spaced holes that can be used with perfboards, breadboards, and 0.1? connectors.\u003c\/p\u003e\n\u003cp\u003eFor good performance, it is \u003cstrong\u003every important\u003c\/strong\u003e to install a large capacitor across the motor supply and ground close to the motor driver.

A through-hole capacitor can be installed directly on the board in the holes labeled '+' and '?' (connected to VM and GND, respectively).

The over-temperature fault provides a weak indication of the board being too hot, but it does not directly indicate the temperature of the MOSFETs, which are usually the first components to overheat, so you should \u003cins\u003enot\u003c\/ins\u003e count on this fault to prevent damage from over-temperature conditions.\u003c\/p\u003e\n\u003ch3\u003eReal-world power dissipation considerations\u003c\/h3\u003e\n\u003cp\u003eThe MOSFETs can handle large current spikes for short durations (e.g. 100 A for a few milliseconds), and the driver’s current chopping will keep the average current under the set limit. The peak ratings are for quick transients (e.g. when a motor is first turned on), and the continuous rating of 13 A is dependent on various conditions, such as the ambient temperature. PWMing the motor will introduce additional heating proportional to the frequency. The actual current you can deliver will depend on how well you can keep the motor driver cool. The driver’s printed circuit board is designed to draw heat out of the MOSFETs, but performance can be improved by adding a heat sink.\u003c\/p\u003e\n\u003ch3\u003eIncluded hardware\u003c\/h3\u003e\n\u003ctable class=\"side_by_side_pics\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ctable class=\"picture_with_caption center\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca class=\"noscript-fallback\" href=\"https:\/\/a.pololu-files.com\/picture\/0J6862.1200.jpg?3923a1056a5c5e895915b9c448f382a5\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cimg class=\"zoomable\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/0J6862_275.jpg\" alt=\"\" data-gallery-pictures='\u0026lt;{\"id\":\"0J6862\",\"caption\":\"\\u003cp\\u003ePololu G2 High-Power Motor Driver 18v17 or 24v13 with included hardware.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J6862.98x98.jpg?3923a1056a5c5e895915b9c448f382a5\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J6862.600x480.jpg?3923a1056a5c5e895915b9c448f382a5\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J6862.1200.jpg?3923a1056a5c5e895915b9c448f382a5\",\"longest_side\":1200}\u0026gt;' data-picture-id=\"0J6862\" data-picture-longest_side=\"1200\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePololu G2 High-Power Motor Driver 18v17 or 24v13 with included hardware.\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003ctable class=\"picture_with_caption center\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca class=\"noscript-fallback\" href=\"https:\/\/a.pololu-files.com\/picture\/0J6861.1200.jpg?be85103d278045e42a7960f510ab2ca3\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cimg class=\"zoomable\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/0J6861_275.jpg\" alt=\"\" data-gallery-pictures='\u0026lt;{\"id\":\"0J6861\",\"caption\":\"\\u003cp\\u003ePololu G2 High-Power Motor Driver 18v17 or 24v13 assembled with headers and terminal blocks.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J6861.98x98.jpg?be85103d278045e42a7960f510ab2ca3\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J6861.600x480.jpg?be85103d278045e42a7960f510ab2ca3\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J6861.1200.jpg?be85103d278045e42a7960f510ab2ca3\",\"longest_side\":1200}\u0026gt;' data-picture-id=\"0J6861\" data-picture-longest_side=\"1200\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePololu G2 High-Power Motor Driver 18v17 or 24v13 assembled with headers and terminal blocks.\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eTwo 8-pin straight breakaway male headers and two 2-pin 5mm terminal blocks are included with each motor driver.

The H-bridge is made up of one N-channel MOSFET per leg; the rest of the board contains the circuitry to take user inputs and control the MOSFETs. The absolute maximum voltage for this motor driver is 30 V, and higher voltages can permanently destroy the motor driver. Under normal operating conditions, ripple voltage on the supply line can raise the maximum voltage to more than the average or intended voltage, so a safe maximum voltage is approximately 24 V.\u003c\/p\u003e\n\u003cp\u003eThe versatility of this driver makes it suitable for a large range of currents and voltages: it can deliver up to 17 A of continuous current with a board size of only 1.3? × 0.8? and no required heat sink. The module offers a simple interface that requires as few as two I\/O lines while still allowing for your choice of sign-magnitude or locked-antiphase operation. A current sense output gives an indicator of motor current, and the driver can limit the motor current to a configurable threshold. The power supply inputs feature reverse-voltage protection, while integrated detection of various fault conditions helps protect against other common causes of catastrophic failure; however, please note that the board does not include over-temperature protection.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating voltage: 6.5 V to 30 V (absolute maximum)\u003c\/li\u003e\n\u003cli\u003eOutput current: 17 A continuous\u003c\/li\u003e\n\u003cli\u003eInputs compatible with 1.8 V, 3.3 V, and 5 V logic\u003c\/li\u003e\n\u003cli\u003ePWM operation up to 100 kHz\u003c\/li\u003e\n\u003cli\u003eCurrent sense output proportional to motor current (approx. 20 mV\/A; only active while H-bridge is driving)\u003c\/li\u003e\n\u003cli\u003eActive current limiting (chopping) with default threshold of 40 A (can be adjusted lower)\u003c\/li\u003e\n\u003cli\u003eReverse-voltage protection\u003c\/li\u003e\n\u003cli\u003eUndervoltage shutdown\u003c\/li\u003e\n\u003cli\u003eShort circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable class=\"specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMotor channels:\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMinimum operating voltage:\u003c\/th\u003e\n\u003ctd\u003e6.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMaximum operating voltage:\u003c\/th\u003e\n\u003ctd\u003e30 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eContinuous output current per channel:\u003c\/th\u003e\n\u003ctd\u003e17 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eCurrent sense:\u003c\/th\u003e\n\u003ctd\u003e0.02 V\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMaximum PWM frequency:\u003c\/th\u003e\n\u003ctd\u003e100 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eMinimum logic voltage:\u003c\/th\u003e\n\u003ctd\u003e1.8 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth\u003eMaximum logic voltage:\u003c\/th\u003e\n\u003ctd\u003e5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth\u003eReverse voltage protection?:\u003c\/th\u003e\n\u003ctd\u003eY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eUsing the motor driver\u003c\/h2\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cp\u003eThe motor and motor power connections are on one side of the board, and the control connections (1.8 V to 5 V logic) are on the other side. The motor supply should be capable of supplying high current. There are two options for making the high-power connections (VIN, OUTA, OUTB, GND): large holes spaced 5 mm apart, which are compatible with the included terminal blocks, and pairs of 0.1?-spaced holes that can be used with perfboards, breadboards, and 0.1? connectors.\u003c\/p\u003e\n\u003cp\u003eFor good performance, it is \u003cstrong\u003every important\u003c\/strong\u003e to install a large capacitor across the motor supply and ground close to the motor driver. We generally recommend using a capacitor of at least a few hundred ?F and rated well above the maximum supply voltage; the required capacitance will be greater if the power supply is poor or far (more than about a foot) from the driver, and it will also depend on other factors like motor characteristics and applied PWM frequency. A through-hole capacitor can be installed directly on the board in the holes labeled '+' and '?' (connected to VM and GND, respectively).

For advanced users who want to customize or enhance their robots with additional peripherals, the robot’s power rails and microcontroller’s I\/O lines can be accessed via 0.1?-spaced through-holes along the sides and front of the main board.\u003cbr\u003e\u003cbr\u003eThe Zumo 32U4 features two H-bridge motor drivers and a variety of integrated sensors, including a pair of quadrature encoders for closed-loop motor control, a complete inertial measurement unit (3-axis accelerometer, gyro, and magnetometer), five downward-facing reflectance sensors for line-following or edge-detection, and front- and side-facing proximity sensors for obstacle detection and ranging. Three on-board pushbuttons offer a convenient interface for user input, and a 128×64 graphical OLED display, buzzer, and indicator LEDs allow the robot to provide feedback.\u003c\/p\u003e\u003c\/div\u003e","brand":"Pololu","offers":[{"title":"Default Title","offer_id":43696845127871,"sku":"MLE04605","price":10499.0,"currency_code":"PHP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/sg-11134201-7rdxz-m1ht1xbpdxz11c.jpg?v=1735811556"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/collections\/Pololu_ff7fd28f-2f3f-466f-9bdb-0738bf5ad947.jpg?v=1721453741","url":"https:\/\/makerlab.ph\/collections\/pololu-philippines.oembed","provider":"Makerlab PH","version":"1.0","type":"link"}
