I'm developing an Arduino Zero based sensor-less ESC (electronic speed controller) for my quadcopter and I am thinking of making it open-source. I may even sell them one day.
Some specs:
- 30 amps continous, >80 amps peak
- 2 to 3S (6.6V to 12.6V)
- Current monitoring
- Various control methods; PWM, I2C, Serial, USB
- ~$10 BOM @1000
- DC-DC converter
- 20mm x 43mm PCB
Version 1
I just wanted to see if anyone would want to use it before I spend the time on the documentation.
