3D Printer LCD Panel Adapter for RAMPS-FD

1. LCD-Panel-adapter-FD is an adapter for Adruino DUE and Ramps-FD, which are always combined to work as a 3D printer control board.
2. Since the working voltage of the Arduino DUE chip is 3.3V, while the LCD works best at 5V, we add a signal amplification circuit in the adapter chip, so that the DUE board can better drive and isolate the LCD display.
3. LCD-Panel-adapter-FD is considered one of the best LCD adapter for DUE + Ramps-FD on the market.
