Add information about the USB port
#Rope on a balloon/drone/kite/etc.. to the rope loop.
#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
The board will communicate with the official GRAWMET software using this approach. Reverse engineering of the port's protocol is underway, however it is believed to use a similar, if not the same protocol the DFM-09(prior generation) uses. A document partially covering this protocol can be found [https://github.com/nickoe/dfm09_hacking/blob/master/fingers-welt/fingers-welt.txt here]
