It’s time to start saying goodbye to F3 boards in INAV. History repeats itself and after we let F1 boards go, the same fate upon F3. Why? STM32F303 does not have enough RAM to handle everything that is demanded of it: OSD, telemetry, GPS, navigation, etc. INAV already is not enabling the majority of new functions on F3 based boards!
What will happen next? Most probably, F3 boards that fail to build due to lacking memory will be removed from the official release process. The code that drives them will stay, but if anyone will want to compile INAV for them, they will have to find missing memory by himself.
So, do not expect INAV 2.4 running on Omnibus F3. On the other hand, SP Racing F3 will probably stay with us for a little longer. Lack of OSD is a huge advantage in this case.
