Hi,
May I know what is the hardware layout for measuring external voltage using SAADC? I may not be understanding the infocenter or the datasheet for setting the external reference pin
Thank you!

Hi Luke
You can try to calibrate your nRF52840 for more accurate measurements. This link should be helpful. As the calibration data get saved in flash, you should just have to do this once.

Hi Luke
I don't think there is much more to do to get the results more accurate when your voltage level range is as big as 4-25V. You shouldn't have to calibrate more than once unless you reset the flash memory.

Thanks alot for your time and the calibration results. In a real world application, simply putting it at the start of the timer should do the job yeah?
