In fact I'd stay away from schottky diodes on this job because of high leakage current at high temperatures. | |
| May 13, 2020 at 4:24 | comment | added | Excalibur | Update: My observations while on site weren't captured accurately. Turning the motor on is actually fine, however it's switching it off that's causing inductive flyback, which is likely triggering overcurrent protection and cutting off the Pi's power. So next weekend when I'm at the site, I'll add a 45v/20A rated Shottky diode, in reverse bias, and I bet that will solve the problem. | |
