: This GitHub repository is generally maintained and contains the latest version of the MMJoy2 GUI tool ( MMJoy2.exe ) and firmware files.

: Supports 6 rotary encoders, Hall sensors (TLE5010/5011), and external 12-bit ADCs.

Sim-building communities regularly host verified mirrors of the latest stable build (typically version or subsequent community patches).

Not every Arduino board works with MMJoy2. The firmware requires a microcontroller with native USB HID support and specific hardware characteristics.

Disclaimer: Modifying electronics requires care. Ensure proper soldering and wiring to avoid damaging your components.

Since the original project site is largely legacy, the most reliable source for the latest stable files and English documentation is the community-maintained GitHub mirror. MMJoy2 Latest Stable Release (v20161101) : Download the complete firmware and software archive. MMJoy2 English Wiki
