M5Stack DMX512 Isolated RS485 Unit

The M5Stack DMX Unit provides a compact interface for DMX512 lighting-control networks. It integrates a CA-IS3092W isolated half-duplex RS485 transceiver, an XLR-3 female connector, Grove serial connection, and a switchable 120Ω termination resistor.

Electrical isolation is specified up to 5kVrms, helping separate the controller side from the RS485 bus in supported conditions. The transceiver supports data rates up to 500Kbps, while DMX512 uses a fixed 250Kbps rate.

Connect Embedded Controllers to DMX512 Fixtures

Use the unit for stage lighting, landscape lighting, decorative fixtures, dimmer control, and DMX512 testing. The Grove interface connects to the host serial port while the XLR-3 connector links to compatible DMX equipment.

Switchable 120Ω Termination

The onboard termination resistor can be enabled where the unit is installed at the end of the RS485 bus. Incorrect termination can contribute to reflections and unreliable communication, so plan bus topology, cable impedance, grounding, and termination across the full installation.

Isolation Does Not Replace Complete Electrical Design

Isolation improves interface robustness but does not eliminate the need for correct wiring, surge protection, grounding strategy, connector pinout verification, and enclosure design. Confirm the DMX fixture pinout before connection because physical connectors alone do not guarantee identical wiring.

Build Repeatable Lighting-Control Networks

Keep the bus topology appropriate for RS485, avoid uncontrolled stubs, use suitable twisted-pair cable, and verify termination at the actual endpoints. For permanent installations, follow the applicable electrical and venue requirements.

Technical setup details are available in the M5Stack DMX Unit documentation.

How can I confirm product compatibility?

Check the product specifications, operating voltage, communication interface, dimensions, connector type, and software requirements before ordering. Compatibility may also depend on your controller, operating system, development framework, library version, and project wiring.

If you are unsure, contact us before purchasing and include your controller model, intended application, power source, and any other hardware you plan to use. We will help you identify the most suitable option, but we cannot guarantee that every product will work with every platform or project.

Does the product come with a warranty?

Warranty coverage may vary by product and manufacturer. If your order arrives damaged, incomplete, or appears to have a manufacturing defect, contact us as soon as possible with your order number, product model, and clear photos or videos of the issue.

Our team will review the information and provide the appropriate next step according to the applicable product and after-sales policy. Damage caused by incorrect wiring, unsuitable voltage, unauthorized modification, soldering, misuse, or operation outside the documented specifications may not be covered.

How long does shipping take?

LogicBoundless provides worldwide shipping, with primary service coverage across the United States, Europe, and Asia. Orders are generally fulfilled from Shenzhen, China, and tracking information is provided after dispatch.

Processing and delivery times depend on product availability, destination, customs clearance, and the selected shipping service. Please review the Shipping Information page for the latest estimated delivery times and shipping conditions.

What is your return policy?

Eligible products may be returned within 30 days of delivery. Returned items must be unused, unsoldered, unmodified, and kept in their original condition with all packaging, cables, accessories, manuals, and included components.

Please contact support@logicboundless.com before sending anything back. Returns made without prior approval may not be accepted. Original shipping charges are generally non-refundable unless the return is caused by a verified product defect or fulfillment error.

Can you help if I have a technical problem?

Yes. LogicBoundless provides practical technical guidance for product setup, wiring, power, communication, code, and configuration issues.

To help us understand the problem efficiently, please provide your controller model, wiring photos, power source, code, library or firmware versions, expected behavior, and complete error messages. We cannot promise that every component will work in every system, but we will help you identify the likely cause and the next practical troubleshooting step.

Can I change or cancel my order?

Contact us as soon as possible if you need to change or cancel an order. We will try to assist before the order enters processing or is handed to the shipping carrier.

Once an order has been packed or dispatched, it may no longer be possible to change the products, delivery address, or shipping method. In that case, the standard return process may apply after delivery.
