To fly autonomous to a certain geo coordinate a GPS is needed. Although it is theoretically possible to use the original orange Parrot GPS dongle it is not advised, the performance is just not good enough for great autonomous flights. The solution that is advised is to use an uBlox GPS module.

uBlox

uBlox via serial

A FTDI TTL 232R 3V3 WE cable is used, where - WE stans for wire ended. 3V3 operates at +3.3V levels (signals only, VCC= +5V)

Pinout colors

TTL - 232R - 5V, TTL - 232R - 3V3 Connector color coding

Pin	Color	Abr.Color
1	Black	BK
2	Brown	BN
3	Red	RD
4	Orange	OG
5	Yellow	YE

How the connector is prepared

1. A sharp knive deep in the outer end, the part where the wire come out, this will damage the first part of the wires, but that is OK, it will be cut of and not be used.
2. Cut a along the whole wire till the USB connector begin
3. Peel ot the wires in the begin
4. Grab all the wires of the cable end stringly in your hand
5. With one continuous pull, pull the wires out of the black outer plastic. With a cut alone the line this shoud go, just apply force.
6. You are done!
