I am using antispark connectors (XT90S) on battery for spark protection. These connectors make first contact via a 5.8 ohm resistor in order to slowly charge large capacitors on ESC’s, and make full connection when the connector is pushed to the end. Thus sparks are eliminated.
Although this is good for eliminating sparks, Pixhawk boots normally at the first contact, when I push the connector further it looses connections and powers down. And occationally when the connector is fully inserted Pixhawk does not boot at all when there is stable 5V at the input.
I believe that quick powering power module on and off produces voltage spikes and PMU at Pixhawk does not boot occationally when voltage level is stably restored.
Any suggestions are welcome.
Best wishes,
Ferit.
