This adaptation board for the GGC adapter allows to plug a 4 line LCD display to the GGC without cable soldering. The board contains the LEDHeat.
The board is shipped with a 6 wire connector if you want to connect the optional Motor, PC/GGC, and Heat switches.
Here is the RepRap panel connected to the GGC.
I don’t sell the RepRap panel, you can find it from any 3D printer shop or from AliExpress.
