Navio2 ADC Input Voltage

Hopefully a quick question for someone: does anyone know the maximum input voltage for Navio2’s ADC channels, specifically those used for voltage and current monitoring? I’d like to be able to provide +5V, but also voltage and current measurements from a custom PCB, rather than using the inline PSU board. Presumably the scaling factor is set in Ardupilot?

Thanks in advance to anyone who answers!

Hello there!

Maximum input voltage is 6.6V, so you should be fine providing 5 volts. Take into account the input resistance of 20KOhm.
