5 volt DC measurement

Hardware

I would like to measure 5 volts dc on a P2 using one of the analog pins. Is this safe for P2?

Thanks
Dan

Only on the VBAT_MEAS pin, which has a built-in voltage divider.

On other pins, you'd need a resistor divider as the maximum input voltage is 3.3V on all other analog pins.

@dbru -

What is your accuracy requirement / acceptable tolerance ?? As @rickkas7 said a simple voltage divider can work depending on your use case .
