M8N GPS Puck Flight Controller Stack Mount

thingiverse

This design allows for the disassembly of an M8N GPS puck and integration of its internal components onto a flight controller stack. After experimenting with the BN-800 GPS module, I discovered it to be extremely slow, particularly during cold starts. Further research revealed that the BN-800 is actually an M8M module, lacking flash storage for GPS coordinates, which contributed to the sluggish startup times in stationary locations. This solution will only work with certain GPS pucks. In the Prerequisites section, I outline the specific puck used for this project. The main requirement is a square (38mm) circuit board on the GPS module. Two STL files are provided: one designed specifically for my puck's circuit layout and offering a lower profile, while the other "tall" version should accommodate most pucks with 38mm square boards. I have thoroughly tested the print, which securely holds the GPS board in place and attaches seamlessly to the flight controller stack. The base is surprisingly flexible, allowing easy removal of the GPS board when the mount is detached from the stack. However, once screwed on, it provides a snug and secure fit. To avoid potential interference with LiPos, the GPS is offset slightly towards the rear, preventing the front edge of the circuit board from protruding into tight spaces.
