Key Features

  • CA-IS3050G isolated CAN transceiver
  • Classical CAN data rate up to 1 Mbps
  • 1000 V isolation reference
  • ISO 11898-2 physical-layer support
  • Current limiting and thermal protection functions

The M5Stack CAN Unit provides a galvanically isolated classical CAN physical layer for industrial controllers, robotics, distributed equipment, test systems, and automotive protocol development. Its CA-IS3050G transceiver converts a compatible host CAN controller’s TX/RX signals into differential CANH/CANL communication at up to 1 Mbps. The isolated power stage improves robustness against common field disturbances. The host must still provide the CAN controller, frame handling, bitrate, filtering, error recovery, and higher-level protocol.

CAN Unit: Core Functions and Control

Connect a Host CAN Controller to CANH and CANL

The unit supplies the isolated transceiver and bus interface while the host generates and receives classical CAN frames.

Operate at Data Rates up to 1Mbps

The practical cable length decreases as bitrate increases, so the final network must be designed for the selected speed.

Separate Controller and Field-Side Grounds

Galvanic isolation helps tolerate ground differences and noise when combined with correct topology and protection.

CAN Unit Applications

  • Industrial CAN gateways
  • Robot actuator and sensor networks
  • Distributed equipment monitoring
  • Automotive CAN development
  • CAN-bus test fixtures

How to Integrate the CAN Unit

  1. Confirm that the host includes a compatible CAN controller.
  2. With power removed, connect CANH, CANL, and the required terminal reference.
  3. Install 120 Ω termination only at the two physical ends and set one bitrate across the network.
  4. Begin with test frames and inspect acknowledgements and error counters.
  5. Implement bus-off recovery, filters, authorization, and safe command handling.

CAN Unit Deployment Notes

  • This unit is for classical high-speed CAN and should not be assumed to support CAN FD data-phase speeds.
  • Isolation does not replace correct cable, topology, shielding, surge protection, or enclosure design.
  • Maximum distance depends on bitrate, cable, stubs, termination, and loading.
  • Do not transmit on an unknown vehicle or machine network.
  • CAN communication alone is not a certified functional-safety layer.

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.

Don’t Just Take Our Word for It
