Arduino Evaluation Board, ATmega328P, 8 bit mega AVR MCU

Romeo BLE mini small Arduino robot control board with Bluetooth 4.0 is a simplified version of Romeo board. It inherits all functions of Romeo BLE. Moreover, it got a smaller size. It has 8 Digital pins, 4 analogue 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. Romeo BLE mini will be a good assistant to Makers. It supports Gravity-3pin interface, modules. It also support external power supply automatically switch, can simultaneously USB and external power supply. Romeo BLE support wireless download program / wireless communication function, mobile phone APP control.
