Logitech G19 Modding with Multi Colour RGB LED's

We choose a Logitech G19 and replaced the inner plastic plate with our electronic board, with one RGB LED for each Key.
The red, green and blue colours are mixed separately in steps between 0..255 .

With 44 Microcontrollers on board, we designed a 387-channel 8-bit LED controller.

Uses 1 of the G19 USB ports for LED programming
- Stand alone mode with several LED effects
- Windows software for LED control and other effects
- Open Protocol for user-programming
