After a long time finally a reliable version of a TMC4671 + STM32F407 kit has been produced.

This version used the AC724 30A current sensors for lower noise and more reliable mosfets and protections for the mosfets as the previously used BSC030N08NS5ATMA1 can briefly glitch on due to the miller effect during steep switching transitions at voltages over 36V.

This issue has been eliminated in this version by using different mosfets and discharge diodes on the gates.

For this an updated setup and tuning tutorial is available:

The STM32F407 is available on Tindie, the full kit now available on Elecrow (at the time of this log).
