1 Features
The TMC5031 evaluation board is designed for evaluating all features of the TMC5031 controller/driver
IC. The STM32F ARM Cortex-M3 microcontroller is used to control the TMC5031. The FLASH memory of
the microcontroller contains a program which configures the controller/driver chip and controls the
communication with the PC via the USB interface and the RS232 interface.
