DFRobot EDGE102-DMX512 lighting controller combines ESP32-S3 MCU and DMX512 protocol chip

DFRobot’s EDGE102-DMX512 is a DMX512 lighting programming controller based on ESP32-S3 wireless MCU designed for efficient management of stage, theater, and venue lighting. With integrated WiFi and Bluetooth, the controller supports wireless programming and control, simplifying the setup of advanced lighting systems. It offers RS485 (master/slave modes) interfaces, I2C, UART, and GPIO pins for compatibility with a wide range of sensors and boards.

This controller enables automation through sensor integration, supporting devices such as infrared detectors, sound level meters, and laser sensors. Its eight optically isolated industrial switch inputs ensure seamless compatibility with PNP sensors, allowing lighting effects to respond automatically to environmental inputs. By reducing dependence on manual DMX consoles, it is well-suited for automated lighting in theaters, stages, and commercial venues.

DMX512 Lighting Programming Controller front and back

The controller supports open-source platforms like Arduino and ESPHome. Detailed information about software setup, hardware connections, DMX512 driver instructions, and example code can be found on the official wiki page.

Previously, we covered the H801 WiFi RGB LED Controller and the LA1016, LA2016, and LA5016 Logic Analyzers supporting the DMX512 communication protocol. We also wrote about the ESP8266-based ANAVI Light Controller and Anavi Light pHAT for light control without DMX512.

DFRobot’s EDGE102-DMX512 lighting programming controller is built with an alloy steel enclosure with support for rail mount and wall mount installations. The package includes the DMX512 programmable controller, a WiFi/Bluetooth antenna, two 35mm DIN rail clips, two mounting brackets, and a pack of mounting screws. It is available for purchase on DFRobot’s store for $59.00.

If they had gone with ESP32-C6 instead then they could add Zigbee and/or Thread support as well.

I think the 3-pin connector was supposed to be the selling point (the Prohibited non-DMX connector, see https://en.wikipedia.org/wiki/DMX512)
