DWM1001C battery measure

Hi all.

Can you advise different ways to measure the battery charge in a Li-Ion battery powered DWM1001C module?

Connecting the battery output directly to a Input digital PIn and detecting in user space when it changes to “low” could be a simple approach? The input pin’s shouldn’t be above 3.6V

What about a resistor based voltaje divider? I think it has power consuming issues. Right?

A battery fuel gauge should be the “pro” solution. Can you recommend some?

Other options?

Thank you very much.

Hi Ramiro (ramg).
If it is still relevant, a small clarification: how and where is it planned to display the results of measuring the battery charge level?

Hi @555dragon. Still planning this, but we are thinking initially in a led and lately using iot data.
Thanks!
