BALA schematics and technical information

[ramaker]

Re: BALA module schematics?
I'm looking too for pinout and schematics for BALA.
I know that there is a link: https://docs.m5stack.com/#/en/app/bala.
But there is no real description - no connectors - no pinout AND NO schematics.
(only one smal picture of the programming interface - useless)

Where is a description - or a manual - or a video - or picturs, were I can see, what I can connext to BALA ?

I wrote an Email to the M5Stack supportt - but no answer.

regards
