As a UAV remote control

You’ll definitely want to check out Reddit user rad_man1234’s full selection of images of their RC solution on the Steam Deck. Whereas some might see the wide open real estate on the back of the Deck as the perfect spot for a kickstand, battery attachment, or hub, rad_man1234 has a whole remote transmission setup slapped to the back of their Deck. Running on Windows and using some software from the Microsoft app store, they can send pulse-position modulation signals to an Arduino from the joysticks on the device. Rad indeed.
