Connection Wires

The schematics of the LED matrix is attached below.

Please follow the following instructions to connect hardwares.

  1. The 8x8 LED Matrix must be common-grounded with the Arduino module;
  2. Connect Arduino pin 8 to DIN on the LED Matrix;
  3. Connect Arduino pin 9 to CS on the LED Matrix;
  4. Connect Arduino pin 10 to CLK on the LED Matrix;
  5. Use independent power supply for the 8x8 LED Matrix Shield, and the supply voltage is 5V/2A.
