Hello all at Endless Sphere. I have been brain storming for the pass few years on the idea of building my own speed controllers based on the atmega328p. My application voltage will be in the range of 60-75v dc and around 200- 300a continous. I found a few LDOs and DC to DC converters that will able me to power the 328p with the 5v required. I do realize Atmel has its own forums for my purpose i just wanted to stop by ES first. Any questions are welcomed thanks for any help and advice.
