Product Details

The TMC7300-EVAL allows you to explore all functions of the TMC7300-LA DC motor driver IC.

The TMC7300-EVAL-KIT is a set of one MCU board Landungsbruecke, a Eselsbruecke bridge board and one TMC7300-EVAL driver board. It allows for a quick and simple start within only minutes to make your motor turning, while still providing full access to all registers and full functionality and diagnostics.

For diagnosis, all signals between MCU and TMC7300 are accessible with probes on the bridge board. TMC7300-EVAL can be used with or without the Landungsbruecke MCU board. .

All you need to get started is a power supply and ADI Trinamic's free and easy to use TMCL-IDE. This graphical user interface allows quick setup and supports the use of commands in direct mode, monitors real-time behavior visualized in graphs, and logs and stores data. All settings can simply be exported for your own firmware project.
