That's a really great resource. I had understood "Rinput - Input resistance - >1M" as an actual resistance, where the blog post suggests it's really an effective load resulting from the sampling rate. Unfortunately, the link referred to for details of this (infocenter.nordicsemi.com/.../saadc.html seems to be broken, as are a number of links on the devzone. Does anyone know the updated location for this information?

Hi,

Q) Do you have any recommendations on measuring the voltage of a lithium battery (e.g 4.2V) using nRF52?

A) Yes, see the blog post Measuring Lithium battery voltage with nRF52.
