DMX - communication module with isolated RS485 transceiver - Unit extension module - M5Stack U183
DMX Unit is a communication module designed for data transmission in the DMX-512 standard . It has an isolated RS485 transceiver (CA-IS3092W) with protection up to 5 kVrms. It communicates with the M5Stack host via the Grove interface (UART) and operates in half-duplex mode. The module equipped with a 3-pin XLR socket makes it easy to connect DMX devices, and the integrated 120 Ω resistor prevents signal reflections. It is ideal for controlling stage, architectural and decorative lighting.

Product description: DMX - communication module with isolated RS485 transceiver - Unit expansion module - M5Stack U183
The DMX Unit from M5Stack is a compact communication module designed for DMX-512 systems , mainly used in stage and decorative lighting control. Equipped with an isolated RS-485 transceiver CA-IS3092W , providing up to 5 kVrms of protection against electrical interference. Communication is via the Grove (UART) interface using the RS485 protocol in half-duplex mode, which allows easy connection to M5Stack controllers. Thanks to the 3-pin XLR (female) connector , the DMX Unit can be directly connected to DMX lighting systems. The built-in 120 Ω termination resistor eliminates the problem of signal reflections at the end of the bus, which improves the integrity of the transmission. The module supports data transmission at up to 500 Kbps (of which DMX-512 uses a fixed value of 250 Kbps). The DMX Unit is a perfect solution for stage lighting control systems, architectural illumination and control of DMX devices.

Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
Communication module for DMX-512 data transmission.
Main Features of DMX Unit
- DMX-512 support - standard protocol for lighting control
- Isolated RS-485 transceiver (CA-IS3092W) - provides up to 5kVrms of interference protection
- Communication via Grove (UART) - easy connection to M5Stack controllers
- 3-pin XLR socket - standard DMX interface for easy integration with devices
- 120 Ω resistor - built-in switch eliminates signal reflections on the RS-485 bus
- Transmission speed up to 500 Kb/s - DMX protocol compliant (250 Kb/s)
- Compact dimensions - 48 x 40 x 25 mm, easy integration with control systems
Compatibility and programming
DMX Unit works with the M5Stack ecosystem , including Core , Core2 , CoreS3 , Atom and StickC . The connection is via Grove interface, using UART and RS-485, and the user must configure the pins in the program code accordingly. Supports programming in Arduino IDE and UIFlow 2.0 . A DMX Unit Library is available, facilitating the implementation of lighting control functions.
Example communication pins for various M5Stack devices:
- Core Basic: TX - G16, RX - G17
- Core2: TX-G13, RX-G14
- CoreS3: TX-G17, RX-G18
- Atom Lite/Matrix: TX - G32, RX - G26
The module communicates via the Grove interface.
It has a standard XLR socket for easy integration with DMX devices.
Practical applications
DMX Unit is used in stage, architectural and decorative lighting control systems. It can be used to control LED lights, spotlights, dimmers and other DMX devices . Thanks to RS-485 isolation, it is suitable for installations requiring high resistance to electrical interference.
