Feather turns off during discharge #39

Open nicholaswilde opened 2 years ago

The Feather turns off during discharge when connected to a high current device such as a mobile phone. This may be due to the voltage drops too low during high current output which drops below the required voltage of the Feather. The Adafruit Powerboost 1000 Basic shuts down when the Feather shuts off because the EN pin on the Powerboost is not pulled high. A work around for this is to manually turn on the Powerboost with a switch that floats the EN pin. The downside is that there isn't monitoring during discharge.

One solution might be to limit the current by using the Adafruit Powerboost 500 Basic instead.
