Yeah I installed the firmware for v4. When I check the ardupilot page for f405 v4 it is showing that motor 1 and 2 grouped together where as 3 and 4 are in group 2. Does it have anything to do with that
You should only need to set MOT_PWM_TYPE
Thanks now it works. It was the firmware. I flashed the speedybeef4v4 firmware as there was no specific firmware for speedybeef405v4. Then I tried the firmware of Speedybee f405 mini and now it works. But the drone is very unstable and yawing
Also getting a prearm internal error 0x4000
So you have the mini? I would like to get to the bottom of this if possible. I have the v4 and the firmware works fine for me.
did anyone get the servo output on this board working? I have tried what seems to be everything and nothing from S9.
Never mind, S9 was a waste of time. M5 works.
