CardKB schematic

[dlakwi]

Is there a complete schematic available for the CardKB?
In the github M5-ProductExampleCodes repository within the CARDKB/firmware_328p there is an image "cardkb_sch_01.png". However, this lists the column and row pins for the keyboard matrix. I'm guessing it's like the FACES keyboard, but I'd like to see the complete schematic.
