Hello everyone. I am using a pixhawk 2.4.8. Everything works fine. The buzzer works, safety switch works, gps works, the battery is okay and the battery monitor is calibrated, rc works and it gives output with it’s controller. But I have a problem. When I try to use a servo motor (for rudder, aereol or elevator) it doesn’t works. I can see the outputs in servo outputs. I change the mode to manuel and arm the device. It arm’s with no problem but the servo doesn’t works. In rc channels servo works, but in main out or aux out pins it doesn’t works. I checked the signal and ground with a multimeter. It returns 4.9V. Can you help me. I can’t solve it?
How are you providing power to the servo rail? The servos require their own power supply to the servo (usually 5V) to the rail. Between signal and ground isn’t enough.
We have a LiPo Battery that is 4S, 40C and 3300 mAh. We checked it and in multimeter it returns 15.9V. It connects to a power module. And it connects to the pixhawks power input. In rc between signal and gnd pins there is 4.9V too and it works on rc channels. Firmware is fmuv2 (plane 4.6.0). Can you help with that?
