DATA SHEET

4X4 (16) matrix of programmable RGB LEDs. Uses 5050 LEDs with built in WS2812B driver. Cascading NRZ Single line interface allows for larger arrays. Each LED requires 8 bits/color (24bits) + a Reset (Latch) for a 25 bit data stream, so 16 would need a data stream of 400 bits.
Sequence is from closest LED to Din to LED last one in string,
NOT like a Shift Register.
Power: 5VDC @ ~1A/16LED Module
Multiple Modules may require additional Power Supply
connections as board traces have limited carry current
Colors: 16 million
LEDs: Red: ~625nm @ ~400mcd
Green: ~522nm @ ~700mcd
Blue: ~465nm @ 190mcd
Min Scan Frequency: >400Hz
NOTE: Programming is not for the inexperienced!
