Question About Extra Ribbon Cable Ports On Banana Pi CM4 Daughterboard

so on the Banana Pi CM4’s daughterboard, the one that the CM4 mounts into that then mounts into the 200 pin connector on the motherboard, there’s two extra ribbon cable ports right next to the CM4. i’ve circled them in this photo

i wanted to ask what these are used for as they seem to be completely unmentioned in the hardware section of the html manual, as well as the backside of the Pocket Reform Magic Poster’s schematics (then again i’m horrible at reading those so that one may be my fault), and the assembly guide never instructed me to plug anything into them. i’m mostly wondering what they route to on the board and/or the CM4 as i’d love to do some research into seeing if i can do something devious with them lol

i see them as an unfulfilled opportunity and would love some direction on this, even if it’s just a “here’s the pinout, good luck”, any help (or pinout guides) would be greatly appreciated

I don’t know the answer except “there should be a pinout here”

There are kicad schematics and pcb files.

I mean these would be the schematics specific to this module vs the poster that maybe does not include it.

perfect thank you! this is exactly what i was after, wasn’t sure where to find them.
