hi! i have a speedybee f405 v4 FC & esc stack and was wondering if anyone knows where to find the ardupilot firm ware for it? I looked on the website and can find the firm ware for all the other F405 models. I tried downloading the F4 v4 thinking that was correct however I it looks like its not recognizing the IMU so I can’t calibrate the accelerometer or anything.
Any help is appreciated, thanks!
