G'day,
I saw on the VESC documentation that it is able to provide 3.3V or 5V to external electronics, on the board I'm assuming this is from the section labelled 'sensor.'
Could someone please tell me if and how I can power some of my own electronics from the ESC like an LED strip/raspberry pi/arduino?
Thanks,
Ed
It depends on a couple of things, the VESC has a +5V and +3V3 regulator and those voltages are pinned out in a couple of places but they're also critical to the functioning of the VESC and if you pull too much current from either the VESC may be damaged/damage itself. Different VESC versions can supply slightly different amounts but at a guess <400mA on +3V3 and <700mA on +5V. So enough for just an Arduino or Raspberry Pi Zero but not much more.
For larger current requirements e.g. a Raspberry Pi 4B or >1m of neopixels it would be better to use a Buck Convertor from eBay or similar to provide a completely separate voltage supply.
