This 8x8 SPI Dot Matrix Module allows you to experiment with dot matrix LED's without all the complicated wiring. The module makes use of the MAX7219 LED driver which handles all the complicated stuff such as multiplexing the LEDs and driving them at the correct currents. What's more, the modules can be daisy-chained over serial interface to make larger LED displays whilst still only requiring 3 digital control pins, making it ideal for your microcontroller projects.
Features:
- Red LEDs
- 5V supply
- LED brightness adjustment can be implemented in software
- Support daisy-chain for larger display
- 3-wire SPI interface
