Pixelblaze V3 Standard XL - WiFi LED Controller

Pixelblaze is a Wi-Fi Addressable LED Controller and Custom Pattern Editor, powered by an ESP32 module with 240Mhz dual-core processor for 'blazingly fast' pixel rendering capabilities.

This is the Pixelblaze V3 Standard which has additional interface and expansion capabilities. It can interface with hardware and sensors using GPIO, analog, or touch inputs. It has an optional Sensor Board with a microphone, accelerometer, light sensor, and a music-reactive co-processor, giving you much more than just volume levels. This is the XL variant with X-tra Large 16MB flash memory and 8MB PSRAM for more data storage than the 'S'mall variant.

Pixelblaze is great for anyone making LED art, large or small, costumes, and wearables, or decorating cars and houses inside and out! With Pixelblaze V3's tools and documentation, it's easy to learn how to write patterns and dissect existing patterns to discover their secrets.

The web-based live editor and highly optimized expression engine make it fast and fun to write new LED patterns. You can store a hundred patterns and write new ones by entering mathematical expressions or code that updates live as you type. Pixelblaze was designed to make it easier to write LED patterns and get an intuitive feel for how code and math impact those patterns.

Sharing and finding patterns written by the community is easy, and there are over 200 patterns available that can be loaded as-is or used for inspiration in your own designs.

And that's not all, pixel maps let you focus on how your pattern looks in 2D and/or 3D space without worrying about coordinates or scaling for different installations. A pattern that works on one LED setup will work the same on a different LED setup.

Write a generative map in JavaScript, or use real-world coordinates in any unit. It supports arbitrary LED configurations without impacting pattern code. Examples include rings, 2D matrices, walled cubes, and volumetric cubes.

Adding UI controls to a pattern is as easy as writing a function. This lets you add sliders and color pickers to a pattern that can be used to adjust the look and feel of a pattern.

Made for LED Enthusiasts and Novices Alike

If you aren’t a coding wizard, don’t worry, many people with limited programming experience have found Pixelblaze’s editor approachable and fun to use.

The real-time editor, instant feedback, a variable watcher, and expression-centric pattern generation mean you won’t have to pull your hair out to find that missing semicolon or curly brace. Even run-time errors that would usually crash your program are harmless and show up right in the editor.

Pixelblaze isn't just made to be friendly; it's also powerful. It really shines in the hands of someone familiar with programming and comfortable writing expressions in a JavaScript or C-like syntax. If you are already doing this with a microcontroller, Pixelblaze was made for you.
