i’m having a problem with the Pixhack V3 controller, in a quadcopter bought to a particular manufacturer.
The problem is, when i connect the batteries x2 6 Cells 22.2 V 488.4 Wh 22000 mAh. to the dron.
The peripherals starts, the gimball stabilizes, the rotors spins, but the main controller won’t start even the main LED don’t start .
When i disconnect the POWER wire from the Pixhack, the controller start, the status LED starts, and the ARM button powers up.
So you are connecting 2 batteries in series to the power module or in parallel to the power module? Because as far as I remember, the Power Modules can not handle more than 6S configuration. I could be wrong , but that was my experience so far
Most Powermodul should deliver five point three Volt. What kind of PM you use? May you can test another one or power suply. If that doesn’t work I would say the pixhack regulator is not healty anymore.
Good test. I think this demonstrates that there is something wrong with the power circuitry inside your pixhack. If you have the ability to exchange or replace it, that’s the best option.
But, if you don’t have the capability to exchange or replace it, you might try the suggestion by @Cipta to provide 5.3V via a power supply. If that works, the problem is actually with your power module, as @Cipta suggests, which is a less-expensive replacement.
The video linked above (at 4:28) called powering the system via the Servo rail a “backup power source.” Does anyone know if it’s dangerous to power your system exclusively this way? (and just leave the “power” input disconnected)
Just a quick note on the above, if you have the breakout USB and led module plugged in- the main LED will not light at all. I can’t tell from your image if it is plugged in but it’s a quirk and I wish it wasn’t a ‘feature’, but it is. This may not be your problem but will hinder your trouble shooting if you aren’t ready for it. 2 6s batteries in series is 12s. The cuav pm is good for 6s maximum so that may be the culprit although I know this has been discussed above. More pictures would help us.
