Products
MoonModules develops and maintains open source lighting software for ESP32 microcontrollers.
Core products
- WLED-MM: the mature fork of WLED, audio-reactive, large fixture support ⓘ
- MoonLight: stage and installation use, DMX and Art-Net, up to 16,384 pixels ⓘ
- projectMM: cross-platform module runtime for ESP32, Raspberry Pi, and PC; the base layer MoonLight is moving towards ⓘ
- FastLED-MM: FastLED combined with the projectMM runtime: a complete ESP32 firmware with web UI, dual-core processing, and REST API ⓘ

Project timeline
Each product grew from the experience of the one before it. WLED-MM has been the main fork since 2022, adding features that moved faster than upstream WLED could absorb. MoonLight started in 2023 as a clean-room redesign with a modern UI, 3D fixture support, and DMX. In 2026, projectMM applied the lessons from MoonLight into a cross-platform module runtime; FastLED-MM builds on projectMM as a minimal but complete firmware for FastLED users.
WLED-MM-Troyhacks is a separate playground for experimental work on the ESP32-P4, capable of driving over 100,000 pixels on Art-Net via Hub75.
Roadmap (April 2026)
- The Audio Reactive module in WLED-MM is being extracted into its own repository so it can be used as a library by WLED-MM, projectMM, and other projects independently.
- WLED-MM continues as a playground for new features; the longer-term aim is to push as much as possible back upstream and minimise the diff with Aircoookie WLED.
- MoonLight 1.0 is due in May 2026. Active development stops at 1.0; the project will be maintained but not extended.
- projectMM continues where MoonLight leaves off. A rename is likely as it grows beyond the proof-of-concept stage.
- FastLED-MM remains a minimal demo application, a reference for how to use projectMM as a library and a working firmware for FastLED users who want Wi-Fi and a web UI.
