The NeoKey FeatherWing adds two mechanical key switch sockets with individually addressable NeoPixel backlighting to any Feather-format microcontroller. Each socket accepts Cherry MX or compatible switches (Kailh, Gateron, etc.) without soldering, using Kailh hot-swap sockets.

A reverse-mount NeoPixel sits beneath each switch, shining up through the switch housing. The two pixels are daisy-chained as a single 2-pixel NeoPixel strand for easy control. A STEMMA QT connector is included for solderless I2C connections to additional sensors and accessories.
