Hey @jamiek / anyone, are you using buck convertor to power your Pi, if so which? Or are you happily powering your Pi off the Octopus board, maybe that’s ok for Pi 3+. But for Pi 4, am less confident.

Octopus User Guide says…
- Max 5V 8A on page 7
- Board has 5V headers (J26) specifically to Power Pi on page 10. Can see J26 Header/Pins, but searching for J26 on Schematic didn’t reveal max current for the header. Am assuming it’s good for what ever the board and J26 dupont pins are capable of (3amp).
Planning to run Pi 4 (acquired during the before times) which consumes ~3.0A, currently leaning towards decided to give the precious Pi it’s own buck convertor power supply isolated from whatever is going on with the Octopus connected steppers/fans/lights/etc… Also thinking probably better (decoupled fate/cycling) for the Pi to not be harshly reset as frequently as how often I need to reset/abort Octopus job.
