Has anyone used one of these?

Come on over to /r/hotasDIY. Best thing to do would be to get an STM32 Bluepill, get a 2 axis joystick from Adafruit (MPN: 245), get a breadboard (MPN: 4539), and some jumper wires (MPN: 1956). Then you can flash the Bluepill with Freejoy firmware and set it up with their configurator, no coding required.

FreeJoy is a nice firmware for a game controller, but the used "Blue Phil" (STM32F103C8 ) boards very poor - build quality, components.
Could someone please explain this to me.

Similar - FreeJoy, but for STM32F103C8 - 'Blue Phil" cards, even more cheap.

No, the joystick base has a gimbal with hall sensors (no wear) and it's fully analog XY sensing. It also has a hall analog twist axis built in the upper handle. It runs FreeJoy firmware on a custom shaped bluepill (STM32F103C8T6). It gets fully identified as a usb joystick and works as normal. It can accept about 25 direct buttons and 8 analog axis, or up to 256 buttons using an array with diodes (that's for simpits, I suppose).
