Turn on and off an Adafruit Powerboost using a Feather.
The sketch can be found here.
EN pin on the Powerboost when shorted to ground turns off the board. A 10kΩ can connect the
EN pind and
GND to cause the Powerboost to be off all of the time and the Feather can be used to drive the
EN pin high, thus turing on the Powerboost.
- It is fine to keep the resistor between the
GNDall of the time.

Overall, the Feather was able to turn the Powerboost on and off without any issues.
The Feather can be used turn the Powerboost on and off. A button connected to the Feather may be used to turn the Powerboost on and off. One issue is that the Powerboost can only be turned on if the Feather is also on. Sometimes when the current draw is to high from the Powerboost will cause the Feather to turn off which will cause everything to turn off. Perhaps a manual switch may be placed between the resistor and ground that will completely float the
EN pin causing to Powerboost to be turned on manually.
