Description
Each matrix has 128 LEDs (64 Red & 64 Green) however there is noticeably not 256 leads. Instead, the LEDs are wired into a matrix. This matrix has the LED’s anodes connected across rows (8 pins) then the red and green LED’s cathodes attached across columns (8 pins each). To light an LED, connect its rows anode to +5volts, and through a resistor, it’s columns cathode to ground. (you can try this without a micro-controller)
