8x8 Red 64 LED Dot Matrix Displays 3mm CA

The 8x8 Red 64 LED Dot Matrix display packs 64 red 3 mm LEDs into a square grid of 8 rows and 8 columns. Each LED can be lit on its own, so you can show letters, numbers, icons and scrolling text. This version is common anode (CA), and it is a classic part for learning multiplexing with Arduino and for building signs, games and clocks.

8x8 Red 64 LED Dot Matrix Specifications

• Matrix: 8 × 8, 64 LEDs
• LED colour: red
• Dot size: 3 mm
• Configuration: common anode (CA): the 8 LEDs on each line share one anode pin, and the cathodes are connected along the other axis
• Pins: 16 (8 anode lines and 8 cathode lines)
• Typical forward voltage: about 2 V per red LED

8x8 Red 64 LED Dot Matrix Applications

• Scrolling text signs and message boards
• Arduino games such as Snake
• Clocks, counters and score displays
• Icons and status indicators in projects
• Teaching multiplexing and display driving

What's in the Box

• 1 × 8x8 red LED dot matrix display, 3 mm, common anode

Tip: Never connect the matrix straight to a supply: add a current-limiting resistor on each cathode line and scan one anode line at a time (multiplexing), or use a driver IC such as the MAX7219, with its segment outputs on the anode lines and its digit outputs on the cathode lines. Pin numbering varies between makers, so test the pins with a multimeter in diode mode before wiring.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
