Power Rock-S0 from GPI pins

ROCK Pi Series
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.

I just tried powering the RockPI-S0 from GPIO pin 2, and I see that the 3.3v outputs are now at 3.6v. Does that mean that the 3.3v regulator is before the GPIO 5v pins? That is to say, that the SBC must be run from the USB connection only for the 3.3v regulator to operate?
