Power Rock-S0 from GPI pins

#1

Can I power the Rock-S0 from one of the +5v GPIO pins instead of the USB connection?
I’m looking to battery-power it directly if possible.

When looking at PiS schematics https://dl.radxa.com/rockpis/docs/hw/ROCK-PI-S_v13_sch_200910.pdf IMO the VCC5V0_SYS is connected directly to USB-C VBUS and used as an input to all the power circuits. Also this net is available on pins 2/4 of the J9101 pinheader, marked as +5V. GND is available there too

So that’s a “yes”? I can power the board by supplying 5v at any of the 5v pins?

Yes, this is how I power my PiS when the USB-C in gadget mode is disconnected:

I’m speaking of the RockPi-S0, not the RockPi-S. Do they work the same?

Radxa is great in releasing schematics for most (all?) of their boards. IMO the S0 schematics https://dl.radxa.com/rockpis0/radxa_rock_s0_v1200_schematic.pdf is quite descriptive - net 5V_IN is both in J2 USB-OTG and pins 2+4 of the pinheader connector (through the ferrite bead R94) - IMO almost same as in S.
