HPWR for external peripherals?

[ashwindec11]

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.

Hi
I think best way is to power them separetly from M5Stack while using same ground line.

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).

@ashwindec11 No, the input to the core cannot be powered from 12v it is only a 5v or a 3.3v.
to use 12v you need to provide an additional adapter. the stackable module have built in power adapters to take the 12v and supply 5 volt to the M5Stack bus

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

The modules use an LM2596sx to drop the power from 12 to 5v befor feeding it to the 5v pin.

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

[ajb2k3]

@ashwindec11 yes, the motors are 12v and are fed from the 12v side of the LM2596SX, the logic and core are fed from the 5v side of the LM2596SX
