My tracker has come along nicely and initial tests look good.

I started out with something similar to the LANMU UNO R3 Atmega328p Atmega16u2 2014
and just added all the bit I needed.

I have mounted the components onto a PCB to keep things secure, but still need to to some final tidying up.

I’ve still got the Arduino sitting loose but with a proto shield on top. I’m still thinking about how I will finish this so I don’t disconnect anything on a rough landing.

The tracker includes a NEO-6M GPS Module with Antenna 

There is a temp sensor on the PCB and also on the external wire.
An accelerometer and a buzzer.

I’ve also fitted a radio transmitter, to send the APRS data. A HX1 made by Radiometrix.

Also in the picture is the Byonics – Microtrak VHF Antenna V6
