Product Details

The TMC6140-EVAL allows evaluation of the TMC6140 in combination with the ADI 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 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.
