Robust 3.3V CAN bus transceiver module based on the SN65HVD230. Ideal for connecting Raspberry Pi, ESP32, and STM32 to automotive and industrial CAN networks with high ESD protection.

Are you trying to connect your 3.3V controller to a high-speed CAN network?

Standard CAN transceivers often require 5V logic, which can be a headache (and a hazard) for modern 3.3V systems like the ESP32, STM32, or Raspberry Pi. The SN65HVD230 High-Speed CAN Transceiver Module is specifically designed for 3.3V operation. It acts as the physical layer bridge between your microcontroller's digital controller and the differential signalling required for a robust CAN bus, ensuring your data survives the high-noise environment of an engine bay or a factory floor.

The Probots Quality Advantage

Don't risk your processor with unverified transceivers that lack proper ESD protection. This module is Probots Lab Verified, tested for signal integrity at full 1Mbps baud rates. Because industrial networks are unpredictable, we’ve verified that this module includes Probots Logic-Safe design features—handling common-mode voltages and protecting your pins from electrical transients. Your module arrives in Probots Secure-Transit packaging.

Specifications

  • Chipset: Texas Instruments SN65HVD230.

  • Operating Voltage: 3.3V DC (Full compatibility with 3.3V logic).

  • Data Rate: Up to 1 Mbps.

  • Nodes: Supports up to 120 nodes on a single bus.

  • Protection: High ESD protection for bus pins; Thermal shutdown protection.

  • Operating Modes: High-speed, Slope control, and Standby (Low Power).

  • Compatibility: Fully compatible with the ISO 11898 standard.

  • Form Factor: Compact breakout with standard 2.54mm pitch headers.

Key Applications & Projects

  • Automotive Diagnostics: Build an OBD-II logger for your car using an ESP32.

  • Industrial Automation: Interfacing microcontrollers with PLCs and motor drivers.

  • Drones & Robotics: Implementing high-reliability communication between sensors and flight controllers.

  • Energy Management: Monitoring battery banks and solar inverters via CAN.

Project Evolution

  • Past Projects (Prerequisites): If you've mastered UART and I2C but found they fail over long distances or in noisy environments, you're ready for CAN.

  • Feature Upgrade: This module unlocks Differential Signalling. While single-wire communication fails due to noise, the SN65HVD230 uses a balanced pair to cancel out interference, allowing cables to run much longer (up to 1km at lower speeds).

  • Effort/Requirements: Intermediate. You will need a CAN controller (built into ESP32/STM32 or external like MCP2515) and basic knowledge of the CAN protocol.

Virtual Technician & Wiring

⚠️ Tech Tip: Always ensure your CAN bus is terminated with a 120-ohm resistor at both physical ends of the line to prevent signal reflections.

Frequently Asked Questions (FAQ)

  • Does this work with 5V Arduinos? It is designed for 3.3V, but it can interface with 5V logic if a level shifter is used. For native 5V, the TJA1050 is better.
  • Is it compatible with the ESP32? Yes, it is the perfect companion for the ESP32’s built-in CAN (TWAI) controller.
  • Does it include the 120-ohm resistor? Most modules have it pre-soldered. Check for resistor 'R1' on the board.
  • What is the maximum baud rate? 1 Mbps.
  • How many devices can I have on the bus? Up to 120 nodes.
  • Can I use this for OBD-II? Yes, it is widely used for vehicle diagnostics.
  • Does it support CAN FD? No, it is designed for standard CAN 2.0A and 2.0B.
  • What wire should I use? Twisted-pair wire is highly recommended for noise immunity.
  • Does it have a low-power mode? Yes, it can be put into standby via the 'RS' pin.
  • Is it better than the MCP2551? The SN65HVD230 is superior for 3.3V systems as it doesn't require level shifting.
  • Can it handle 12V or 24V bus voltages? The bus lines (CANH/L) can, but the VCC must be 3.3V.
  • Is it compatible with Raspberry Pi? Yes, it is the standard transceiver used in Pi-CAN hats.
  • What is the common-mode range? -2V to 7V.
  • How long can the wires be? Up to 1km at 50kbps; ~40m at 1Mbps.
  • Does it protect against short circuits? Yes, it has built-in bus-fault protection.
  • Is it industrial grade? Yes, the chip is rated for industrial temperature ranges.
  • What is the "RS" pin for? It selects the mode (High-speed, Slope control, or Standby).
  • Can I use it with the MCP2515? Yes, they work perfectly together for MCUs without a built-in CAN controller.
  • What happens if I swap CANH and CANL? Communication will fail, but the module is usually protected against this error.
  • Is the chip genuine? Yes, we source verified SN65HVD230 transceivers to ensure performance.
