Keybow 2040 Circuit Diag, SDK support

Hi
I would like to play with the Keybow 2040 in the SDK so was wondering if there is a circuit dagram avaiable for Pin mapping etc ?
Is SDK support planned ?

Many thanks and regards

I realise some time has passed since this was posted but i would also like to know if there is sdk support planned for the device as if i buy the product i would like to ensure that i would be able to use the TinyUSB library with it etc.
@bobtrex as for circuit diagram you can find that here: https://cdn.shopify.com/s/files/1/0174/1800/files/keybow_2040_schematic.pdf?v=1629994431

Ok
Before I try to create support for Keybow 2040 for the PICO SDK has anyone (including PIMORONI) done anything towards this ?
