Add analog input to V4

[cervantesg]

Hello, I have a Freematics Vehicle Data Logger V4, we are working on a project where they want to log GPS, temperature and some digital inputs (count door opening).

Can we reuse this logger so some input pins can be used to read analog and digital inputs instead of OBD2?

Regards

There are two analog input pinouts on the PCB board (near the LED) accessible as A0 and A1 in Arduino.

What about digital inputs?

I believe ATmega328's analog pins can be used for digital I/O too. They can even be used as software serial.
