Provide clarification on swd power
#Power on the device by pressing and holding the button, you will see a yellow light blink, hold until the light turns solid.
== Mini USB Port ==
The mini USB port on the board does not use the USB protocol for communication, it is a UART bus. However using USB to power the board should not harm the board in theory.
In order to use it, splice a USB cable and wire up a USB<->TTL adapter with the following pins:
* VBUS: 5 Volts DC* D-: TX* D+: RX* GND: GND
When lab testing, you can power the board from the USB header. It also appears to run fine supplying 3.3V to the SWD port(STLink clones do this).
