It inherits all functions of Romeo BLE. Moreover, IT GOT A SMALLER SIZE! Yes, you got it all. It has 8 Digital pins, 4 analog pins and integrates Bluetooth 4.0 wireless communication function. It can easy to drive the mobile platform using two 1.2A H-bridged Motor Driver to meet the needs of small scale robots. We hope Romeo BLE mini will be a good assistant to makers.

TB6612 has the same control logic with L298 motor driver. The code will be compatible with Romeo robot control board. And it finally breakouts 2 interrupt pins now! You can connect encoders to make PID motor control.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003eRomeo BLE mini Projects:\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-494.html\"\u003eHow To Make an Arduino compatible Bluetooth Tank with Custom Android Application (V1.0)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-525.html\"\u003eHow to Build a BB-8 Robot\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-543.html\"\u003eHow to Build a Smartphone-Controlled Robot for Arduino In Only 1 hour\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/blog-694.html\" target=\"_blank\"\u003eHow to make a Wobbly Penguin Robot for Arduino\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch2\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eSupport\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/gravity\" target=\"_blank\"\u003eGravity\u003c\/a\u003e-3Pin interface, color-coded, compatible with servos and Gravity sensors \u0026amp;
