Product description
Compact motor driver for two brushed DC motors or a single stepper motor (unipolar or bipolar). Operates from 4 V to 16 V and supports up to 3 A continuous current per channel without the need for a heatsink, thanks to discrete MOSFET H-bridge design.
Built-in test buttons and motor output LEDs allow quick function testing without connecting a host controller. The integrated buck–boost converter provides 5 V output from as low as 4 V input, suitable for powering a microcontroller.
MDD3A is compatible with logic levels from 1.8 V to 12 V, making it suitable for Arduino, Raspberry Pi, PLCs, and more. Reverse polarity protection prevents damage from incorrect power connections.
