NRF52832 Power Optimization

[CharlesCurt]

Hi All,

I am new to embedded low power design and would love some tips on power saving steps and tutorials for the nrf52832 device.

I am trying to understand the power modes and how I can get into uA current draw while ble is active. Also trying to understand selective powering of Ram, GPIO and the adc.

any help learning this would be awesome!

Here is a comprehensive guide, it is written for nRF51, but is still much relevant:

Here is a blog about the Online Power Profiler, which makes it possible to measure current consumption during BLE event, gives information about current for different components during BLE event and the average current over a specified interval.
