USB-C Power / 5 Volt

@Rene_Hegewald

is there another way to supply the board with 12 V besides the USB-C port ?

Yes.

@sam_Tu

we have no other 12V connector to supply the board

There are no other connector. But if you dont mind soldering and hacking your board. There is a “hack”.

Let's build a laptop

In that case you can supply anything from 5V upto 24V, u might be able to direct power the board with a few 18650s (as long as the output voltage is within 5-24V, that should be 2-5 pcs of 18650 in series)
