Hello everyone,
I'm a home cockpit builder and developer.
Over time I ran into the usual problems many of us face: multiple boards, needing to write code, manual encoder setup, complicated wiring, and separate solutions for buttons, encoders and lights. I developed a single board that tries to solve these issues.
What it addresses: Multiple boards needed → Everything on one board Coding / Arduino knowledge required → Configured with a Windows app, no coding
Manual encoder pin assignment → Encoders auto-detected by turning the knob Multiple USB connections → Single USB-C (HID + CDC) Hard to debug wiring → Live pin monitoring Backlight only works with the sim running → PWM dimmer works even with the sim closed
Main specs:STM32H743
61 native inputs + 16 via MCP23017 (77 total)
Up to 25 EC11 encoders with auto-detection
1 ms sampling
DCS-BIOS support for LEDs
Size: 114 × 60 mm
It appears as a normal 128-button game controller. Here are some photos of the board and the panel it is installed in:[Upload your photos here]Happy to answer any technical questions.
Best regards
