Overview

The TMCM-1290-TMCL is a compact, highly integrated single-axis stepper motor controller and driver module designed for bipolar stepper motors up to 2.1A RMS. It operates across a wide supply voltage range of 4.5V to 36V DC and utilizes the TMCL protocol for sophisticated motion control commands via RS-485 or SPI interfaces.

Why Choose This Part

This module combines Trinamic's advanced technologies, including StealthChop2 for noiseless motion and StallGuard2 for sensorless homing, into a small 24mm x 20.5mm form factor. It reduces development complexity by offloading real-time motion calculations to the onboard TMCL firmware while offering 2047 bytes of EEPROM for standalone script storage.

Applications

Laboratory Automation
Precise liquid handling and sample positioning using StealthChop2 for silent operation in noise-sensitive environments.
Robotic Actuators
Integrated StallGuard2 and CoolStep features provide sensorless load detection and energy-efficient current control for robotic joints.
Semiconductor Manufacturing
Compact footprint and high-resolution microstepping ensure smooth, accurate motion for wafer handling systems.
Factory Automation
Reliable RS-485 communication and onboard status LEDs facilitate easy integration into distributed industrial control networks.
