BALA schematics and technical information

  • Re: BALA module schematics?
    I'm looking too for pinout and schematics for BALA.
    I know that there is a link:
    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.
