Hi guys,
I can't seem to find the document describing the maximum and minimum voltage that the ADC can handle. I'm referring to the 42pin GPIO header. They're numbers 9 and 10 (ADC_IN0 and ADC_IN2).

Thanks!

Hi @ballsystemlord

If you have a look at the schematic at http://wiki.t-firefly.com/en/Firefly-RK3399/hardware_doc.html ,
you'll find both of ADC_IN0 and ADC_IN2 are pull up by 1.8V.

Therefore the minimum and maximum voltage will be 0V and 1.8V .

Hi @penguin! Thanks for your reply.
I did read that document before posting and I still don't see the pin. Which page is it on?
Thanks!
