is EM-406 port compatible, with a built-in power regulator. On the
bottom side, the PCB has an easy to solder pad area (you can also solder
pin headers) allowing you to build your custom cable. The pads included
are "EN" that enables or disables the device; it will just shut down
the device for power saving (just leave unconnected if not used), "5V"
(power supply), "OUT" (data out), "IN" (data in) and "GND" (ground). The
included blue LED will blink while the GPS is searching for satellites
and will remain lit when the satellites are fixed (and ready to go!).
that the new MediaTek has custom and exclusive "DIYDrones" firmware
allowing the unit to output an efficient and very compressed binary
protocol. You can still change between NMEA and Binary protocol with
standard MTK messages, and switch the refresh rate between 1hz to 10hz,
or set any standard serial baud rate (by default it is set to 38400 bps
and custom binary protocol).
An Arduino example for decoding the
custom binary protocol is provided. Remember to install the library
folder "GPS_MTK" inside the Arduino IDE "libraries" folder
"\arduino-00XX\libraries\\". The library and the source code is located
