i build a custom PCB based on Benjamin's schematic v6.4 in ring shape.
It is used in a DIY diver propulsion vehicle. I did small modifications (remove NRF, change some parts) and add a custom app to the firmware to use hall sensors for trigger and speed-adjustment.
I think my modifications to the firmware are fare away from the way, how to do it correct. Maybe someone can help me to do it right
comments are appreciated
