Adafruit Feather nRF52 Bluefruit LE POWER OFF/ON

by prasadcvs on Thu Jul 02, 2020 3:42 am

Hi,
My Adafruit Feather nRF52 Bluefruit LE can be powered by USB or Lipo battery. This setup is also charging Lipo Battery.

In this scenario, how can I POWER ON/OFF the Adafruit feather board without interrupting the charging process? In the picture my Adafruit feather is being powered by USB and simultaneously charging the battery. Now how can I switch off the feather without interrupting the charging of the battery?

You can use the ENable pin (between the BAT and USB pins). Connecting it to ground will disable the 3.3v regulator and cut power to the circuitry. The charging functionality is not affected by this.
