   ok! lets hope this is the one (4th revision). next steps: order pcbs, build, test, and hopefully ship ^^

   because i realized the bpi-cm4 is hardwired to only support 3v3 gpio, i switched over most things to 3v3 and was able to even remove 2 level shifter ICs.

     fun fact: i started this adapter design at home when i was feverish after my very first covid vaccine shot—in may 2021. so this has been brewing since more than 2 years?!

     @mntmn Been there, done that...

     "turns out that pin is already used for SPI flash on the module we use, so we cannot actually use it"
     "oh we can use every pin for input except the one we picked here..."

     That's how https://github.com/das-labor/badge-2021 evolved. xD

     Hey @mntmn I just saw that a RK3588 board with 32GB memory is now finally available for preorder here:

     https://turingpi.com/product/turing-rk1/

     Would that be interesting for (pocket) reform, would that work with the adapter potentially?

     @sfs hi, at the moment we have settled on t-firefly iCore as a RK3588 module because it has mezzanine connectors instead of card edge. other card edge modules are hard to adapt mechanically, it would make more sense to spin alternative motherboards (carriers) then...
