PRODUCT DESCRIPTION
The CJMCU 64-bit 8×8 RGB LED Driver Development Board features a large 8×8 matrix of 64 WS2812 RGB LEDs. Each LED can draw up to 60mA, meaning at peak brightness, the matrix can consume over 3.5A at 5V. To ensure reliable operation, it’s recommended to use a 5V, 2A power supply, with most users experiencing a current draw of about 1-2A per panel.
The board includes two 3-pin connection ports for wiring. To power the board, solder wires to the input port: connect the 5V and ground pins to your power source, and link the DIN pin to your microcontroller (e.g., Arduino). Be sure to connect a common ground between the power supply and the microcontroller.
You can easily chain multiple panels together. For the second panel, connect the DIN pin to the DOUT pin of the first panel, link the ground pins, and power all panels with 5V. Keep in mind that when connecting four or more panels, memory limitations may arise if you’re using an Arduino Uno, and you might need a 5V, 10A power supply for large setups.
Each panel uses a single data line with a specific timing protocol that requires a real-time microcontroller (8MHz or faster) such as an AVR, Arduino, or PIC. The back of the board includes solder pads for wiring or breadboard connections, along with two mounting holes for easy installation on various surfaces.
