Do i need to consider the pins that are used for the controller when using expansion board?

  • Hi!

    Should i consider the pins that are used on the Gpys pinout when selecting gpios to use on the expansion board?

    I see that there are only input pins from P13 to P18 on the gpy, would then these pins not work as GPIO pins when using the expansion board?

    As well, should we avoid P5 to P7 on the expansion board because of LTE?

  • @Erling-Devold P13 to P18 are input only pins due to the ESP32. That's not related to the expansion boards. You can uses them as GPI pins (input only). And yes, if a module pin is connected to a peripheral on the expansion board, you should not use it for other means.
