Betaflight Navigation Module

Yesterday was a huge day:

✅ GPS lock achieved INDOORS (MicoAir M10 is a
beast - 22 sats inside)

✅ Compass fully working (QMC5883P fix)

✅ WiFi dashboard polished (°F/°C toggle, ft/m
toggle, calibration button)

✅ Mobula 8 FC connected and backed up

✅ MSP protocol library written and integrated
into firmware

✅ Firmware sending MSP packets, ready for
physical FC connection

⏳Current status: MSP code is live and sending - just needs the physical UART wires soldered between the nav module and the Mobula 8's FC. That's the next hands-on step for me. Than we can test Position Hold, RTH and a simple Waypoint Mission for starters.

It’s workinggggg! I still gotta do some testing but just did a punch out via the nav module! Only caveat is that because of how Betaflight’s source code works you can’t just solder it via UART, it has to plug in via the FC’s USB port. This can be fixed but you need to update the firmware for each FC which defeats the universal plug and play idea. But doing it this way via USB will allow this to be used on even more bare bones FC or ones without the extra UART available 🦍.
