The Pinout

To interface with and power the graphic LCD, there are two, parallel 8-pin headers above and below it. Flipping the board over, you'll find the labels for each of the pins.

Pin Number Pin Label Pin Function Input/Output? Notes
1 VCC Positive power supply Input Supply range is between 2.7V and 3.3V
2 GND Ground Input  
3 SCE Chip select Input Active low
4 RST Reset Input Active low
5 D/C Mode select Input Select between command mode (low) and data mode (high).
6 DN(MOSI) Serial data in Input  
7 SCLK Serial clock Input  
8 LED LED backlight supply Input Maximum voltage supply is 3.3V.

The Control Interface

       Built into this LCD is a Philips PCD8544 display controller, which converts the massive parallel interface of the raw LCD to a more convenient serial one. The PCD8544 is controlled through a synchronous serial interface similar to SPI. There are clock (SCLK) and data (DN) input lines, and an active-low chip select (SCE) input as well.
       On top of those three serial lines, there is another input -- D/C -- which tells the display whether the data it's receiving is a command or displayable data.

      For a list of commands, check out the "Instructions" section of the PCD8544 datasheet (page 11). There are instructions to enable clearing of the display, inverting the pixels, powering it down, and more.
