Hi all,
I have APM 2.5.3 unit, EMAX Multirotor 25A Simon K Brushless ESC and AX-2810Q 750KV 3S-4S Li-po Brushless Motor.
When I power the board using USB for testing I get a message PREARM NEED 3D FIX. I havent got any reading for GPS. The board passed the initial setting without problems.
I tested GPS unit with my old board apm 2.5.2 and this one can read more than 7/8 satellites. I would like to use this board but I cannot use input 1 as anything plug into it doesn't work.
Anyone any advise?
