8Bitdo does have a gyro controller, I have the Ultimate 2. It does have some requirement to configure the gyro though, you have to boot it in `dinput` mode by holding down a button.

I have included a link from my notes, I have not actually tested it much beyond seeing that the gyro does work in steams "configure controller" thing, never got around to correctly mapping any game.
