A compact 8×8 red LED matrix (KWM-30881CVB) measuring 30.5 mm (1.2") per side. The ultra-bright red LEDs are arranged in a grid with 16 pins (8 per side) on standard 2.54 mm (0.1") pitch, allowing the display to plug directly into a breadboard with one row of pins on each side.

The matrix requires 1:8 multiplexed control. It can be driven using shift registers (such as a 74HC595 for anodes and TPIC6B595 for cathodes) or a dedicated LED driver like the MAX7219, which handles multiplexing automatically.
