Product Details:

Specifications:

  • Drives an 8 x 8 common cathode lattice
  • Operating Voltage: 5V
  • Dimensions: 5 x 3.2 x 1.5 cm (L x W x H)
  • LED Color: Red
  • Four mounting holes with 3mm aperture
  • Includes input and output interfaces; supports cascading multiple modules

Wiring Instructions:

  1. The left side of the module is the input port; the right side is the output port.
  2. To control a single module, connect the input port to the CPU.
  3. For multiple modules in a cascade, connect:
    • First module's input port to the CPU
    • First module's output port to the input port of the second module, and so on.

Connections for 51 MCU:

  • VCC → 5V
  • GND → GND
  • DIN → P22
  • CS → P21
  • CLK → P20

Important Notes:

  1. Ensure VCC and GND are not reversed to avoid damaging the chip.
  2. If using a 51 microcontroller P0 port, connect a pull-up resistor (recommended: 4.7K–10K).
  3. Install the lattice first into the round hole, then into the PCB board, and solder it. Align the lattice face with words from left to right with pin order 123456; PCB board's 1st pin is a square pad.
  4. For electrolytic capacitors, the long pin is positive, and the short pin is negative. Ceramic capacitors have no polarity.

Package Includes:

  • 1 x LED module
  • 5 x Dupont lines (20cm each)
