Drop module or radio transmitter

[erik79]

Hi
I was wondering if anyone know of a module built for accessory bay where the controller can trigger a delivery/drop function, or initiate some other function other than camera. DJI fans have developed drone fishing platform, and I thought solo community did more add on prototypes. I am also looking into attaching a radio transmitter for pushing a message through a radio. Can I use a trigger on the drone to activate something like that from the controller. On the dji they trigger using the led light.

You can accomplish this already using the pause button on the controller and tapping into the mainboard pins it utilizes pwm out I used this for the retracts on my custom build, here is a link to the hack Extend 3DR Solo Accessory Bay - Hackster.io
