The Inkplate platform is really neat. Sorry to see they shipped yours without the MCP23017. I used one of those pins for my project: https://hoytech.com/tabpla

I used one of those pins for my project: https://hoytech.com/tabplate/ https://hoytech.com/tabplate/ But probably some of the GPIO pins on the ESP32 are usable (unless they're reserved for the touch pad buttons on the front, I can't remember).
