LCD 2004 Smart Controller
Easy connect it to your Ramps board using the “smart adapter” included.
After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card.
Further more actions like calibration, axes movements can be done by adjusting the rotary encoder on the Smart Control panel.
3D Printer Accessories Set meets most needs. Including CNC Shield V3.0, UNO R3 Board, A4988 StepStick Stepper Motor Module.
