DFRobot DFR0351 Romeo BLE Mini Arduino Robot Control Board with Bluetooth 4.0

The Romeo BLE mini is a simplified version of the Romeo board. It inherits all the functions of the Romeo BLE. Moreover, it's smaller.It has 8 digital pins, 4 analogue pins and integrates Bluetooth 4.0 wireless communication function. It can easily drive a mobile platform using two 1.2A H-bridged motor drivers to meet the needs of small scale robots. The Romeo BLE mini will prove to be a very good assistant to Makers. You can also check out the Bluetooth micro-controller selection guide to get more information.Version update: V2.0 has an upgraded motor driver IC. It replaces the HR8833 with a TB6612 motor driver chip. The TB6612 has the same control logic as the L298 motor driver and the code is compatible with the Romeo robot control board. It also has 2 interrupt pins now, so you can connect encoders to make a PID motor control.
