Evaluation Kits


The evaluation board TMC429+TMC26x-EVAL provides an excellent, simple and cost efficient device to explore the latest generation of TRINAMIC stepper motor chipsets. The board contains the 3-axes motion controller TMC429, the three coolStep™ stepper motor drivers TMC260, TMC261 and TMC262 as well as the incremental encoder interface TMC424.


You will learn everything about the usage and features of the chipset (coolStep™, stallGuard2™, 256x µstepping, spreadCycle chopper, etc.) and get the possibility to explore your stepper motor motion control application. The evaluation PC-software gives access to every single bit of the chipset. Communication is possible either via USB (virtual COM port) or via RS232.


The TMC429+TMC26x-EVAL is a complete “plug and play” solution. It comes with the evaluation software, a USB cable and all relevant pluggable screw connectors. Additionally only a PC, one to three stepper motors and a power supply are required.
