TMC5072-BOB
Overview
The TMC5072-BOB is a breakout board for the TMC5072 dual-axis stepper motor controller and driver IC. It enables independent control of two bipolar stepper motors from a 5V to 20V supply with up to 1.1A current per motor. The board integrates Trinamic proprietary technologies like StealthChop for silent operation and SixPoint ramp controllers for sophisticated motion profiles via an SPI interface.
Why Choose This Part
This breakout board simplifies prototyping by providing easy access to the TMC5072 SPI pins and power stages without requiring custom PCB fabrication. It includes the StealthChop voltage-mode PWM for near-silent motor standby and low-speed operation, and the SpreadCycle cycle-by-cycle current control for high-speed performance.
Applications
Getting Started
Connect the board to a microcontroller like an Arduino or ESP32 using the SPI interface for configuration and motion commands. Power the VM pin with a motor supply between 5V and 20V, ensuring common ground with the logic supply. Use the Trinamic TMCL-IDE software and a USB-to-SPI adapter for rapid parameter tuning before writing firmware.
