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. Features

* Configurable motor power supply via onboard jumper

* 5V motor power supply: drives four 5V DC motors at one time

* Adjustable motor power supply: drives two 1.25V-6.45V DC motors at one time (9V external power supply required)

* Onboard dual H-bridge driver L293D x 2

* Each L293D can drive 2 DC motors or 1 stepping motor at one time

* 600mA output current (peak 1.2A) per single bridge

* ESD protection
