DFRobot EDGE201 DMX512 ESP32-S3 Lighting Controller

Overview

The DFRobot EDGE201-DMX512 (SKU: DFR0944) is a professional-grade lighting programming controller built around the ESP32-S3 dual-core processor paired with a dedicated DMX512 protocol chip. The dual-core architecture separates user programming (handled by the ESP32-S3 with WiFi and Bluetooth) from real-time DMX512 signal generation (handled by the dedicated chip), communicating internally via I2C for maximum reliability.

The controller features 8 optically isolated digital inputs compatible with PNP industrial sensors, enabling automated lighting triggered by motion, sound, or other environmental sensors. A single relay output allows switching high-power devices, while RS485 with selectable master/slave modes and a 120-ohm termination switch supports daisy-chained communication. The onboard RTC maintains time with less than 3 seconds drift per month, enabling time-based lighting schedules even during brief power outages.

Housed in a rugged alloy steel enclosure with DIN-rail and ear-mount options, the EDGE201 is built for permanent installation in stage venues, commercial spaces, and entertainment environments. It accepts 12-24V DC power and programs via USB-C, supporting both Arduino and ESPHome firmware for flexible integration into existing smart lighting and home automation ecosystems.
