The Tic T834 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, IC, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a TI DRV8834 driver and male headers and terminal blocks areincluded but not soldered. It can operate from 2.5V to 10.8V and can deliver up to approximately 1.5A per phase without a heat sink or forced air flow (or 2A max with sufficient additional cooling).
