Summary

LED driver module using the IS31FL3731 controller with I2C interface. Supports audio-reactive LED modulation, picture rendering, and animations.

Description

The IS31FL3731 LED driver is a matrix LED controller with built-in audio modulation and animation playback features. It communicates via I2C and allows frame-based LED control for creating pictures, patterns, or dynamic animations. Audio modulation can be enabled with configurable gain and blink period settings. This makes it ideal for visual effects, displays, and audio-synchronized LED projects.
