Hi,
On a 3DR quad arducopter, I am powering the APM2.5 with JP1 off and using the 5v input from the 3DR power module BEC (connects through the voltage measurement port).
This powers , If I understood correctly, all of the APM2.5 boards including the Analog I/Os pins and the input pins.
The maximum power delivery of the 3DR power module is 5,37V x 2,25 Amps. I wonder if this will be sufficient power if I connect two servos for the roll/tilt camera stabilization on the Analog I/o pins number 10 & 11 ?
If this is not enough power, how can I feed more power to these analog pins ?
Tx for help and experience on this,
Hugues

Thx a lot that makes it clearer.
I think you will have enough power. The APM is drawing unto 500mA max, the servos draw that much each when moving ie. add 1A, so you 725ma to spare. If you want a supply with more capacity, you will need not to connect the middle pin and supply the 5V from a separate BEC (aka regulator). you will only need to connect the signal line and GND from the analog connection. (you always need a common ground)
