Recommendations for future boards

@BigCorvus your board is really nice. Here's some ideas for the future:

make the SWDIO header more standard (the small ARM 2x5 micro footprint?) or at least througholes so it is easy to solder a header

How to program bootloader

Download from here: https://github.com/adafruit/Adafruit_nRF52_Bootloader/releases

nrfjprog -f nrf52 --eraseall
Erasing user available code and UICR flash areas.
Applying system reset.

nrfjprog -f nrf52 --program feather_nrf52840_express_bootloader-0.3.2_s140_6.1.1.hex
Parsing hex file.
Reading flash area to program to guarantee it is erased.
Checking that the area to write is not protected.
Programming device.

Then reboot the board, if all went well it now shows up as a mountable filesystem on your USB bus.
