DJI just released iNav OSD 2 page font support in their later gen vtx and goggles.
The least expensive setup is O4 lite and Goggle N3 for $109 and $229, respectively
Moderate rework of the DisplayPort code will be needed to support this dual font page setup.
I propose to obtain a setup and work on developing the code.
Planned amount $$ (USD): $366 incl tax
Estimated time for completion:
1-1.5 mo
