I hope some more of you have had luck getting your REF-0s running

My earlier write-ups were focused on the bare minimum connections and code
needed to make a REF-0 work. Of course, external connections are not ideal
for long-term operations. The real end-state here is to have a nice board
with a modern GPS that will install cleanly inside the REF-0. I have
completed another write-up showing my work toward that goal. I show how you
can access all of the necessary pins on the REF-0 directly on the board,
without using the external Interface connector. I also show a simple
prototype of my custom REF-0 GPS board.

Here's the write-up:


If you just want to solder something together, you can easily house your
microcontroller and GPS on some protoboard as I did. This is the protoboard
I used, it fits almost perfectly where a real Oncore GPS would go. I just
had to widen the mounting holes with a drill.


Beyond the prototype though, I personally want a nice PCB with a Ublox on
it for my REF-0s. I plan to work on that as I have time. Though now that my
summer break is over, time is a bit harder to find. :)
