Smart LED Controller with Signal Conditioning

---

Overview

This module supports both 1-pin WS281x smart LEDs and 2-pin smart LEDs (clock and data). Beyond standard LED controls, DUELink standard library includes support for graphics on WS281x matrices.

The control signals coming out of the module are 3.3V logic levels by default. Optionally, you can supply 5V on the Vsig connection to convert the control signals to 5V.

Key features • WS2811 LED Controller • 2-pin Smart LED Controller • 5V Control Signal Option • Support for DAT/CLK type • Terminal Block Connection • 32x22mm overall dimension
