TMC6140-EVAL – MEV Elektronik GmbH
Our Products


The TMC6140-EVAL allows evaluation of the TMC6140 in combination with the TRINAMIC evaluation board system, or as a stand-alone-board. It uses the standard schematic and offers several options in order to test different modes of operation.

The TMC6140-EVAL-KIT is a set of one MCU board Landungsbruecke, one Eselsbruecke bridge board and one TMC6140-EVAL driver board. It allows for a quick and simple start within only minutes to make your motor turning.

For diagnosis, all signals between MCU and TMC6140 are accessible with probes on the bridge board. TMC6140-EVAL can be used with or without the Landungsbruecke MCU board.

All you need to get started is a power supply and 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.

Please use the latest nightly build version of the Landungsbruecke firmware when using the TMC6140-EVAL: Github/TMC-EvalSystem
