I built an Arduboat from spare parts I had on my desk and am having some issues. Everything works fine as long as the servo is unplugged. When I plug the servo in, the sik radio loses connection, my FPV camera dims, and the flight controller beeps. I assume the servo is drawing too much power but it is well within spec of the flight controller.
What I’ve done:
- Checked continuity between the servo pins, looks like there is not a short anywhere.
- Servo is receiving 5 volts
- Swapped the servo for a smaller 9 gram (that’s all I had) and it worked for a while. Original servo was buzzing when I plugged it in.
- Unplugged servo, everything else seems to work fine.
