INFO
The TMC428A evaluation board allows you to explore all func-
tions of the TMC428 and to develop your TMC428 applications.
It is equipped with the TMC246A and TMC249A motor drivers
for high performance motor control. You will learn everything
about the usage and features of the chipset and get the
possibility to explore your motion control application and to
optimize its parameters. The evaluation board comes with a PC
software which gives you access to every bit of the TMC428.
The TMC428A-Eval is a complete „plug and play“ solution, ad-
ditionally only a PC, a motor and a power supply are required!
