First try at a BLE Gherkin
The PCB has several routing problems and so the matrix does not work without a lot of cutting and jumpering.Will be working on a revised board. Probably remove the reset button since the Adafruit Feather BLE already has one. Will look at adding the connector for the battery on the PCB so that a power switch can be added to disconnect it from the Feather when not in use. I will probably remove the LEDs too, probably just add a few status LEDs instead of a full backlight.
The LIPO connector is very large on the Feather. Much larger spacers ~14-16mm will be needed even with low profile sockets.
