My Powerfeather has worked fine for about a year. However now the red LED on my Powerfeather will not stop flashing when the power is on, without or without a battery connected to the charging port. I can load simple sketches but I understand that I should get it back to factory settings.
I am advised to use the Adafruit WebSerial ESPTool but this process seems unnecessarily complicated. Is there any quick and simple way to get a powerfeather board back to its factory settings?
