Dual FOC ESC based on ESP32-S3FN8

[StefanH]

I'd love to have some feedback on a dual channel (motor) ESC based on the ESP32-S3FN8. The board is pretty small and should hold its own at up to approx 30A continuous input current. It's meant for for 6S (25V) setups, but should work from approx 3S.

Did I miss anything on the ESP32-S3 side of things?





The board looks like this:

That looks very nice! Note that I don't think there is a requirement to run VDDA from a different power supply (but I'm sure it's no issue to do so anyway).

Thanks!

I wanted VDDA to have the same supply (and reference?) as the current amps and ~1.6-1.7V '0A' voltage. Given the board layout (the supply IC is close to the ESP) there wasn't much downside in running the extra traces imho.

I left LNA_IN floating, would it have been better to tie it to ground?
