The Graphic LCD screen is a backlit TFT LCD screen with headers. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.

This is the step that I wish I had been able to find more easily when I started with this board. After I received the screen and realized I didn’t know how to hook it up I turned to the Adafruit guide for their product.
At first, it looked like the pin layout was different but otherwise, the two displays were interchangeable and able to run the Adafruit Graphics library (more on the code in the next step). However, when I hooked up my board following the Adafruit guide, my display sort of work. It did display text and drawings, but there was a lot of noise in the image and the images were streaky down the screen. It also had a bright glow along the top of the screen that interrupted the image quality. I thought it was because I was running the screen on 5V and it needed lower power. I tried 3.3V and the display got worse. After about 10 minutes of regretting my eBay purchase and wishing I had gone with the Adafruit board, I decided to google my problem and found this helpful article about a similar problem:
In short, you need 1k Ohm resistors between 5 of the connections. You can see where the resistors go in the Fritzing diagram. The second picture is a table of the connections between pins on the display and Arduino. I’ve listed them below and indicated if the connections require a resistor.
RST – Arduino Pin 7 – 1k Resistor
CS – Arduino Pin 9 – 1k Resistor
DC – Arduino Pin 8 – 1k Resistor
DIN – Arduino Pin 11 – 1k Resistor
CLK – Arduino Pin 13 – 1k Resistor
Vcc – 5V
BL – 5V
GND – GND
