The Trinamic TMCM-1043 manual provides specifications, wiring diagrams, and setup instructions for the step/dir driver board.
The TMCM-1043 is a compact 1‑axis driver board for 2‑phase bipolar stepper motors. It is controlled via step and direction signals and can be mounted directly on the back of a NEMA‑17 motor. The board includes an on‑board processor for initialization and diagnostics, as well as error and additional outputs.
Key features include a fixed 1.1 A RMS drive capability (1.6 A peak) with programmable up to 1.4 A RMS, a wide supply voltage range, high microstep resolution, and spreadCycle™ chopper technology. The manual covers wiring, configuration with the USB serial programmer kit, safety cautions, and revision history.

It accepts nominal supply voltages of 12 V to 24 V DC, with a maximum of 28 V DC.
Never connect or disconnect the motor while the board is powered; always disconnect the power supply first.
No, the module will short any reversed supply voltage.
