TMC5271-EVAL Evaluation Board User Manual
Evaluation manual for the TMC5271 stepper motor driver, supporting 1.6A RMS coil current, 2.1-20V DC supply, and advanced features like StealthChop2 and StallGuard4.
Overview
The TMC5271-EVAL user manual describes the evaluation platform for the TMC5271, a high-performance step/direction driver for two-phase bipolar stepper motors. The board supports up to 1.6A RMS (2.24A peak) current and operates within a 2.1V to 20V DC supply range. Key features include SPI and single-wire UART communication, 1-256 microstepping, and proprietary technologies such as StealthChop2 for silent operation, StallGuard4 for sensorless load detection, and TriCoder for steploss detection. The document provides hardware setup instructions for single and dual-supply configurations, connector pinouts, and guidance for using the TMCL-IDE software for tuning current, velocity, and position modes.
