4-Channel Motor Control Shield for Arduino [Discontinued]

Build an awesome 4-wheel drive robot with your Arduino Uno using this 4-channel motor controller shield from Waveshare!

The shield is capable of driving 4 DC motors or 2 stepper motors at one time thanks to the dual L293D motor drivers pre-installed on the board.

The motor power supply is configurable via the onboard jumper selector - either choose 5V to run 4x 5V DC motors, or select the adjustable power supply option to choose between 1.25V-6.45V (via external 9V power supply).

Also onboard is a power selector switch and power LED, linear 5V regulator, terminal blocks for motors and handy stepper motor pinouts.

A full user wiki is available to show you how to use the shield. Note: Board will get warm during use.
