I have an APM2.5 board and I am building my first hexacopter, so the first build seems harder.
Now I am trying to understand the basics of powering of the APM board. At first, do I understood correct, that if JP1 jumper is not set, I should power both inputs and outputs? And if it is set, I should power either inputs or outputs, isn't it?
The second problem I have with my BEC (built-in the ESC). Its output voltage is 5,67 V which is greater than recommended 5.00 +-0.5V. Could the difference in 0.1V cause troubles?
