Nucleo Dongle - Feather Adaptor

Remove the USB Type A plug from the dongle and add a Adafruit Micro B breakout board. It is convenient to have a Micro-SD breakout board (level shifter is not needed) and JTAG connector (I prefer the 14 pin STM variant to have a serial interface by the ST-LINK). Everything mounted on headers on the backside of FeatherWing Tripler Mini Kit.
