CNC Stepper Motor Driver Shield Ramps 1.4

Description

CNC Stepper Motor Driver Shield Ramps 1.4 is a stepper motor driver adapter in the form factor of an Arduino shield, particularly for Mega 2560 compatible boards. It is designed for the purpose of using Pololu stepper driver boards such as the A4988 or DRV8825.

Ramps can only work when it is connected to an Arduino Mega 2560 and a stepper driver such as the A4988 or DRV8825. Owing to its stability in operation and great compatibility with most 3D printers (all RepRap models, such as the Prusa i2 and i3), the combination of Ramps 1.4, Mega 2560, and A4988 or DRV8825 is becoming a mainstream choice for DIY 3D printer control boards.

Features:

• Standard interfaces (as that of the extruder)
• Reserved GCI like I2C and RS232
• 3 MOSFETs are applied to the heater, fan, and thermistor circuit
• Adding another 5A fuse to protect the component parts
• An 11A fuse is added to the hotbed
• Supports 5 stepper driver boards
• The adoption of pin headers makes it more convenient to repair or change
• I2C and SPI are reserved for expanding
• All the MOSFETs can be controlled by PWM
• Adding an SD module for SD Ramps module
• LED can indicate the status of the heater (the open and close of MOS)
• 2 stepper motors for the Z axis in parallel
