Supports up to 128 buttons, rotary encoders, and switches.

Now, go build that cockpit. The sky is not the limit—your USB port is.

Utilize matrix wiring or shift registers (like the CD4021 or 74HC165) to maximize inputs. mmjoy2 download updated

Look at your Pro Micro board and locate the (Reset) and GND (Ground) pins. Briefly bridge these two pins twice with a paperclip or wire to force the board into bootloader mode.

When extracting the downloaded files, avoid using spaces or non-English characters in the folder path. Use a simple path like C:\mmjoy2 to prevent upload errors. Supports up to 128 buttons, rotary encoders, and switches

Spending 30 minutes hunting for the version is a rite of passage for DIY sim builders. The payoff is a professional-grade USB controller that rivals a $300 Thrustmaster or Virpil unit for less than $20 in parts.

The Arduino bootloader only stays active for about 8 seconds. Check the "Auto-start upload" box in JoySetup to catch the port the moment you reset the hardware. Utilize matrix wiring or shift registers (like the

Use a small wire or tweezers to quickly short the RST (Reset) and GND (Ground) pins twice in rapid succession. The onboard LEDs will begin flashing or changing intensity, indicating a 7-second window where the board is ready to receive firmware.

Perfect for radio stacks, trim wheels, and autopilot panels.

This typically means the MMJoy2 firmware hasn't been successfully uploaded. The Arduino Leonardo's default firmware is still present. Re-flash the .hex file, ensuring you selected the correct chip type and COM port.
