Description

This 2-channel CAN bus expansion HAT is engineered specifically for Raspberry Pi, offering high-reliability CAN 2.0 communication. It employs a robust dual-chip solution with two MCP2515 CAN controllers and two SI65HVD230 (or SN65HVD230) CAN transceivers, enabling two independent CAN channels for demanding applications.

Designed with industrial and automotive environments in mind, the HAT incorporates multi-onboard protection circuits. This includes integrated power isolation, which eliminates the need for an external power supply for the isolated terminal, and a digital isolator for secure, stable, and interference-resistant signal communication. Further enhancing its ruggedness, an onboard TVS diode provides essential ESD and transient peak voltage protection, while a voltage translator allows for flexible 3.3V/5V logic level selection via jumpers. SPI control pins are also broken out for interfacing with other host controllers like STM32 or Arduino.

Key Features

  • Standard Raspberry Pi 40PIN GPIO extension header, ensuring broad compatibility with Raspberry Pi series boards.
  • Adopts MCP2515 CAN controllers and SI65HVD230 (or SN65HVD230) CAN transceivers for 2-channel CAN communication.
  • Integrated power isolation provides a stable isolated voltage without requiring an extra power supply for the isolated terminal.
  • Onboard digital isolator for signal isolation, enhancing communication safety, stability, and anti-interference capabilities.
  • Onboard TVS (Transient Voltage Suppressor) diode for ESD protection and transient peak voltage protection.
  • Onboard voltage translator, allowing selection of 3.3V/5V operating voltage via jumper configuration.
  • Onboard 120Ω terminal resistor, configurable by jumper to match bus requirements.
  • Breakout SPI control pins for versatile connectivity with external host control boards such as STM32 or Arduino.
  • Comes with comprehensive online development resources and a detailed manual to facilitate integration.
