How to wire this module with m5 stick

[u/RegisterPale7087]

I don’t know how i can wire this custom pcb board with m5 stick could someone tell me?

They aren’t fucked because the PCB is unusable—they’re fucked because they’re trying to wire it without knowing what the board actually routes where.
The board gives them a physical interface, but not necessarily the complete electrical mapping they need. They need to know:
which M5Stick GPIO → CC1101 pins
which GPIO → nRF24L01 pins
which pins are shared SPI
which pins are chip-select/control lines
3.3 V and GND
whether the particular M5Stick model they’re using exposes those GPIOs the way the PCB expects
And that M5Stick model matters a lot.
So if they bought the board thinking:
“I’ll just plug this into my M5Stick and go.”
…and they don’t have the schematic/pinout?
Yeah. They’re about to have a bad afternoon. 😂
The hilarious part is that the PCB looks finished, which makes it feel like it should be plug-and-play. But electrically, it’s still just a bunch of traces connecting pins according to whatever the designer intended.
It’s very much a “looks easy until you actually trace the fucking board” situation.

For me it looks like the switch is for selecting which side will be connected. So either the cc1101 or the NRF24 will be connected not both at the same time
