Most power efficient way for PWM on nRF52

[Milan]

Hi Team,

There are many ways to implement PWM in nRF52.

Can someone help me understand which is the most power-optimized way along with the softdevice? Using PWM peripheral or PWM using timers and gpios?

Thanks!

Depends on the PWM frequency and resolution that you need. Slow PWMs may be more power efficient when using RTC as a timer source, as the PWMx peripherial keeps the HF clock running.
