Wanhao Duplicator 4 3D printer motherboard.
I received this board as part of some other items but as I don't do 3D printing I've just shown it powered up. I am told the board does work fine though.
It says Rev A on the board itself, uses an ATMega 1280 and has 5 stepper motor drivers mounted on it.
You will receive the motherboard, keypad/SD card board and connecting cable only.
The LCD display board and cable is not included in the sale but just pictured to show the version etc.
