Parrot Mambo Pins

Does anyone know what the pins on top of the Parrot Mambo do like which ones send a signal to the grabber/cannon or power or some other function?

it is a USB connector : D+, D-, Vbus and GND

Ah ok, so does that mean that the parrot grabber attachment has its own PCB that interprets the signal or how is the command to close and open passed to the grabber?

Yes, accessories have a small chipset in it.

Ah ok that’s unfortunate

Is the chipset available for purchase possibly or is it proprietary?
