Romeo BLE mini is a simplified version of Romeo board. 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. And 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.
Version Update: V2.0 has upgraded its motor driver IC, it replaces HR8833 with TB6612 motor driver chip. 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.
