Hi Stanley, thanks for the response.

Got my package this weekend and I started looking at the code first since I can't access my vehicle just now.
Forgive my ignorance, a couple of (noob) questions:
- How can I use other display drivers? I want to use SSD136 driver. There are libraries for Arduino ...

Hi all,

while waiting for my kit, I wonder whether the 2 external GPIOs can be used for an external OLED display?
That would really turn the ONE+ box into a multifunction unit.

Cheers,
Florian

Can the external GPIOs be used to connect an I2C device? This would be an easy way to expand GPIOs, e.g. using a chip like this: https://www.instructables.com/id/IO-Exp ... d-Arduino/

I know it's an old thread. Did you find out how to use additional GPIOs?
