This motor driver shield plugs onto a compatible microcontroller board and uses L293D driver chips to control motor speed and direction. It can run up to 4 bi-directional DC motors or 2 stepper motors, and it has 2 dedicated servo connectors.
Large screw terminal blocks make motor wiring quick, while pull-down resistors keep motors off at power-up and a reset button is easily accessible. Size is approximately 70 x 54 x 18 mm.
