Add modified board photo, edit serial protocol type.
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://githubwww.comgraw.de/nickoeproducts/dfm09_hackingradiosondes/blob/master/fingersps-welt15/fingersPS-welt15] uses.txt here]
== Hardware modifications ==
[[File:Modified DFM-17 Radiosonde.jpg|thumb|332x332px|MrARM's modified DFM-17 with a SWD connector and a SMA antenna.]]
The DFM-17 has solder pads for an SMA port and a SWD header.
An [https://adafru.it/4048 Adafruit Skinny SWD SMT] connector and a generic SMA connected was used in the photo.
