A discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.8×0.8-inch board supports a wide 5.5 to 30 V voltage range and is efficient enough to deliver a continuous 25 A without a heat sink.
The new version of the Ardubot PCB breaks out all the Arduino pins to a separate row of headers. It also includes spaces for LEDs, a reset switch, and servo headers.
This version of the micro serial servo controller is packaged as a partial kit in which the surface-mounted components are already assembled. Male header pins are included, but you can also connect your servos directly to the PCB if space or weight are a concern.
