Ah okay, so what does HPWR do? And aren’t the motors 12V?

Ah okay, so how does the stepper module work for power? Also what is HPWR?

That could be a way but I want to keep everything together (otherwise why use something nice and concise like M5Stack when I could just use a breadboard with wires everywhere and multiple power inputs). The input for the core can be 12V so I thought why not use that as the input for the other stuff (heater, fan, motor, etc).

I have a project where I need to power some 12V devices; what would be a good way to achieve this? I see the HPWR label but which pins would I use as the M5Bottom re-assigns them (and the base26 has 2 set as R2/T2 with the 3rd as Vin). So far I’m thinking attach a header to base 26 then use the Vin pin and a ground pin and maybe use another for the logic.
