INFO
The TMC211 is a single chip microstepping motor driver and
motion controller with integrated sequencer, bipolar stepper
motor driver and LIN slave interface. It is specially intended for
de-centralized mechatronic functions. A user-programmable OTP
memory is integrated to store motor parameters and configu-
ration settings. The TMC211 allows up to four bit of micro
stepping and is capable of driving a phase current of up to 800
mA peak. After initialization, it performs all time critical tasks
autonomously based on target positions and velocity param-
eters. Together with an inexpensive microcontroller the TMC211
forms a complete motion control system.
For using the evaluation board together with the PC software a
USB-2-X interface is needed.
