- Page 3 TMC236 / TMC239 Evaluation Kit 1 Introduction The TMC236 evaluation kit and the TMC239 evaluation kit make it possible to evaluate the features of the TMC236 and TMC239 stepper motor drivers. An evaluation kit contains the following things: • An evaluation board equipped with either a TMC236 or a TMC239 stepper motor driver an an AT90S2313 microcontroller.
- Page 4 Always turn off the power supply before a motor is being connected or disconnected, as otherwise the motor driver may be destroyed!
