DFRobot Romeo V2 Robot Control Board with Motor Driver

The Romeo V2 from DFRobot is a control board for robots, compatible with the Arduino Leonardo, with a motor driver for two DC motors and a socket for Xbee. The ATmega32U4 handles USB itself and has a second serial interface, so programs can be uploaded without removing a radio module. The motor driver delivers 2 A continuously per channel and also controls a stepper motor. Five buttons on the board are for testing, sensors are connected to coloured 3-pin headers.

Recommended Accessories:

0.8m Micro USB 2.0 cable black

Features:

ATmega32U4, Arduino Leonardo bootloader, Micro-USB
Motor driver for 2 DC motors or 1 stepper motor, 2 A each
Supply via USB or external, automatic switching
Switch separates the motor supply from the system supply
