Inkplate 6MOTION - Free GPIO pins
Inkplate 6MOTION's onboard STM32H743 has some pins reserved for internal use (for example, the connection to the e-paper display) and cannot be used for end-user applications. This page contains a list of the available GPIO pins that can be used for external applications.
⚠️
If you don't need pin details and are just interested in the pins, here are the Inkplate 6motion that are not connected to any external component:
The onboard ESP32-C3-WROOM-02 is used as a Wi-Fi co-processor and therefore cannot be used for other purposes
