Made progress on the schematic

Im attempting to use the data sheet to build a schematic, however it is getting quite confusing in places

For the schematic to be done i still need to:

  • place some terminals for VS and the motor coils
  • work out what to do with "SDMODE" and "SPIMODE"
  • the data sheet also talks about "Tuning the MOSFET Bridge" but it looks really intimidating

i also managed to find some cheap mosfets that look quite promising on LCSC

decrypting this into something i could understand was also interesting

i plan to have a board that goes into the step stick port, and then uses JST-ZH cables to connect to the board with the actual drivers and other things

the TMC5160 data sheet has been scary and confusing in that there are sooo many abbreviations and things im needing to try and work out on the go.
However i am grateful for at least having too much information and not too little, because i would lost far more often if the data sheet wasnt so detailed
