How to use GPIO on ODROID-N2+?

Installation Home Assistant OS
1

Hi Forum,

I am running Home Assistant on the ODROID-N2+ board (the nice blue one!) and would like to use the onboard GPIO ports, but how to take control? Or would it be more easy to get I/O with an extended or remote GPIO solution?

These boards seems to be fully ready for GPIO usage:
BeagleBone Black GPIO (bbb_gpio)
Orange Pi GPIO (orangepi_gpio)
Raspberry Pi GPIO (rpi_gpio)
remote_rpi_gpio (remote_rpi_gpio)

Did you ever figure this out?

I’m in the same boat and have been running a secondary HA install on a RPi 3 just for gpio support.

Hi Jonathan, i still didn’t figure out how to access the the onboard GPIO of the Odriod-N2+ … When I bought the Blue box last year I was expecting a full adoption of this powerfull board and that the GPIO support will come any soon, but unfortunately. I am planning to start using ESPHome, I might start with the Olimex ESP32-POE-ISO to get myself started… now i need to find spare time.

Thank you for the update.

I was also considering using an ESP32 as a solution since the GPIO pins on the ODROID still are not functioning.

As of update 2022.2 all integrations interfacing with GPIO directly, have been deprecated. It might happen that GPIO (for RasPi) will return in HACS, but it seems to be better to move to external hardware to make GPIO possible.

Update, GPIO for RasPi is available in HACS:

Waste of time.

An other easy to use GPIO solution is Firmata.
