I think the FOC_KING will need these switches in order to be a true KING. I’ll add them, why not?

You don’t want to use current filters on a low side shunt design.

The phase voltage filters are a good idea though.

The sampling data looks pretty noisy. There is a similar issue with the 75200 and it caused a lot of problems running motors smoothly.

How to update firmware on the Flipsky 75100 & 75200 FOC ESC

There are a few differences between the MakerBase 75200 and the Flipsky one. The 75100 of both models uses 3x INA181 current sense amps which seems to work fairly well. The 75200 they went with a quad op amp instead of 3 current sense amps. The MakerBase one uses the SGM8584 while the Flipsky version uses the SGM8634. It’s unclear if this was a change batch to batch, an attempt to fix something, part availability, or something MakerBase does different. What was clear is the fact that the no…

4 layers instead of 2 layers would probably help a lot by having ground planes close to the signal lines for a short current return path.

Cool to see the progress on this project!
