Hello everyone, I was wondering what the analog input in the gemma can take (0-5V, 4-20mA etc). I am looking to connect an IR sensor to it and what to make sure I select the proper output. Please advise!

The analog pin can read voltage levels between 0 and 3.3v.

Re: Gemma V2 AI
Can this be set to a digital input or will I just have to use a threshold?

It can also be used as a digital input or output.
