32x16 Red Green Dual Color LED Dot Matrix - 7.62mm Pitch [DE-DP14211]

A 16×32 dual-colour LED dot matrix panel with red and green LEDs at 7.62mm pitch. Each LED can display red, green, or both simultaneously for yellow — giving three colour options per pixel. Four HT1632 matrix scanning processors on the back handle the display multiplexing, so once you write the LED states, the panel takes care of refreshing.

The panel connects via a 16-pin IDC cable and requires 5 digital pins from your microcontroller (plus one extra pin per chained panel). Panels are chainable — connect the output of one to the input of the next for larger displays.
