Overview

The TMCM-1210 is a compact single-axis stepper motor controller and driver board designed for mounting on the rear of NEMA 8 (20mm flange) stepper motors. It integrates a motion controller supporting linear and sixPoint ramps with a bipolar stepper driver capable of 256 microsteps per full step. The module features stallGuard2 for stall detection, an on-board 12-bit hall sensor for absolute position sensing within one rotation, and an RS485 interface for remote control. It operates on a supply voltage of 7V to 30V DC and delivers a programmable motor current up to 0.6A RMS. The document provides detailed mechanical dimensions, connector pinouts for JST PH series interfaces, and electrical operating ratings.
