I reread it, but the information is not publicly available. Contact them directly? I haven't tried. Maybe they can help. Thanks for your time. I'll write back later; maybe someone will be interested.

Have you tried to reach out to the manufactur? https://www.mouser.at/datasheet/3/2627/1/MYD-LT527-SX.pdf Website: en.myir.cn Email: sales@myir.cn Tel: +86-755-22984836

Thanks. Regarding Android, it seems to be the most optimal. But I was still hoping someone would have a schematic

Without schematics, deep knowledgde and a lot of time to waste, this task is probably close to impossible. Only chance I see here is for once assuming the vendor is lazy and the implementation is as close to reference design as it can get. And for the other that there is some android device tree which can be reverse-engineered.

This is a MYD-lt527m-16e2d-180-e-sx board. Allwinner T527 chip. The seller isn't helping. It's hard to figure out how the peripherals are connected.
