This is a basic Flight Simulator Autopilot panel It uses a STM32 chip and can be used with FreeJoy firmware: https://github.com/FreeJoy-Team/FreeJoy It behaves as a joystick so you need to assign the different functions in FS. The 3D printed flanges are available attached in the project as well as the FreeJoy configuration file. All the SMD components are available as standard parts for the JLCPCB assembly service, except the USB port because they don't provide any connectors. The tactile buttons, encoders and screws (ref C357370) are available at LCSC, but the encoder shaft is about 10mm too long. The PEC12R-4220F-S0024 can be used if you don't want to cut the shaft and file the bottom part. I used these knobs: https://www.aliexpress.com/item/4000111276637.html
