I will start working on videos and tutorials and add links to them here.
See the readme here for complete instructions on how to flash the MicroAPRS firmware in both MacOS and Windows.
For now, there is something I want to address about the GPS module. Originally, I chose a GPS module that had a really small antenna. After using it for a while, I realize the antenna is very poor at reception. So, I decided to use a different model with a larger antenna.
As is turns out, the model I originally used has a different pinout than most other models that have the larger and better antenna.
However, there is a solution for the current versions of the board (currently v1.2). You can simply shift the board one pin over and solder a jumper from the vcc line to the pps through-hole (not used otherwise).
Additionally, I do plan to change this in the next board revision.
