Wireless Motor Driver Shield: https://www.sparkfun.com/products/14285
Two new robot chassis kits let you level up your robotics game with small, desktop-sized bots! We’re also releasing a revision of the Ludus Wireless shield, which we’re calling the “Wireless Motor Driver Shield.” The shield has an onboard motor driver and breakout pins for servos, analog sensors, and an I2C port. We also added a separate power jack for powering your motors separately from the Arduino.
