Has anyone looked at adding support for the BetaFPV V3 1s 12A AIO?

Hello!
So after a temperature calibration that i’ve done by the board itself, I finished to configure the MTF-01 (optical flow/Lidar). It works, but inconsistently. I have a few question from where I am now:

-This board does not has a compass (right?), wich parameter have I to set and how? I read that for copters, a compass is mandatory.

-Can I log some .bin files on an external support? (ideally my computer)? The memory of the board allow at least 9 minutes of logging, that’s why I could’nt make a whole temperature calibration as detailled on “How to methodically configure and tune any ArduCopter” I tried different things but only managed to get a Tlog file (by setting log backend type) As I need to fine tune my copter, It would be great to have a solution for loggin (maybe external SD reader on serial port?)

-I have an EKF3 issue “EKF3 IMU0 STOPPED AIDING”, and that since I installed and sat up the MTF-01. Any advice on a parameter to change, and what would be the risks around that issue?

Thank you,
Julien
