DFRobot Romeo BLE Mini - Small Robot Control Board with Bluetooth 4.0 and Motor Driver Based on Arduino

INTRODUCTION 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. FEATURES Support mobile phone APP control Two-way H-bridged Motor Driver Support servo external power input Supports AT commands to configure BLE Support serial transmission Support master and slave switch SPECIFICATION BLE chip: TI CC2540 Transmission distance: 30m (open area) Microprocessor: ATmega328P Board selection: Arduino UNO Flash: 32 KB (ATmega328P) of which 0.5 KB used by bootloader SRAM2: KB (ATmega328P) EEPROM: 1 KB (ATmega328P) Clock Frequency: 16 MHz Digital I/O Pins: 8 PWM Digital I/O Pins: 4 (D3, D9, D10, D11) Analog Input Pins: 4 Output current: 1.2A single-channel continuous drive current Start / Peak Current: 2A (continuous pulse) / 3.2A (single pulse) Motor Drive Pins: D4, D5, D6, D7 microUSB connector 2x2A H-bridge motor driver Size: 45x38.5mm SHIPPING LIST Romeo BLE mini V2.0 x1
