This compact motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a 4.5 V to 28 V operating range and can deliver continuous output currents up to 2.6 A (5 A peak) without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.
