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

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).

Cool project. Thanks for sharing.
