Access Solo/Pixhawk 2 aux 1/relay pin

Hi guys!

Have anyone tried to access aux 1 (pin 50), (or other aux ports and ground pin) in 3DR Solo (Pixhawk 2).  I need it to trigger a Sony camera with cam_trig_type: relay, which is quite trivial on pixhawk 1.  3DR support wouldn't help me out with this..

  • Anyone have some picture with the pin of mainboard et the position of RC9/ RC10 ?

    It's for connnecting a cable Gentled for shutter RX100.


  • the aux pins are disconnected from the accessory bay. if you want aux pins, you'll need to either tap into them from the main board or connect the aux pins to the respective points the accessory bay connector.
