Middlesex County, Ontario | My ATV setup is an antenna, micro F9P, HC05 bluetooth module, small adapter PCB, USB battery bank, 3d print, and some hardware store parts like a 4" electrical box cover, pipe flange, and 1/2" pipe nipple. The battery life is about 24 hours.
I'm using micro F9P's for all my tractors, base station, etc. I've shared the files for the small adapter PCB here: https://github.com/WildBuckwheat/SimpleRTK2B-Micro-breakout-board
If you have the standard arduino size F9P then you can buy a bluetooth module with Xbee footprint from Ardusimple that plugs right onto your F9P and that would have the same functionality as my contraption.
I've gone through some iteration of my boundary making processes.
At first I simple connected the bluetooth to my windows tablet running AgOpenGPS. Just sync the bluetooth and setup AgIO to read the right COM port. Connect to my NTRIP base station in AgIO same as normal. I made the boundaries directly in AgOpenGPS.
Then I started playing with different Android Apps. SW Maps is the app that I've settled on. For me when I'm on the ATV or walking, the phone is easier to handle than the windows tablet. The app has settings to connect to your base station. You make your boundaries directly in this app and transfer them to AOG.
I've found that editing boundaries in AOG or the phone app is tedious or difficult. Trying to get everything structured perfect during recording on the first try is also difficult. What I do now is record data with the phone app, and then take that recorded data from the phone app and import it into a desktop program called QGIS. QGIS is a free and full featured GIS program. Inside QGIS I can touch up boundary points, make interior boundaries for things like waterways, and I can do things like make parallel offsets or curves of specified radii. This workflow is more complicated than just recording in AgOpenGPS, but it is much more flexible. I can for example record the location of the tops of fence posts, then inside QGIS I can stitch those points into a curve, offset the curve 2', and use that offset to form the boundary for that side of the field. Then use straight recorded points for the second side of the field, but with a smoothing applied. Make the third side of the field a straight line parallel to the first side. Etc, anything is possible with QGIS. Now I can just go out with my phone app and capture data, not having to worry about it al being structured and organized perfectly, I just sort it out later in the office.
With my portable F9P I can also do other neat things like
- Use the GNSS Master App on an android phone and have a battery powered base station.
- Connect to AOG tablet and have battery powered GPS guidance/lightbar
