2-Channel Isolated CAN Expansion HAT for Raspberry Pi

2-Channel Isolated CAN Expansion HAT for Raspberry Pi

Overview

The 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supports CAN2.0, features multi onboard protection circuits, high anti-interference capability, and stable operation. It suits for fields such as automotive devices or industrial automation.

Features

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication
• Integrated power isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal
• Onboard digital isolator, signal isolation makes the communication more safe, more stable, and better anti-interference
• Onboard TVS (Transient Voltage Suppressor) diode, provides ESD protection and transient peak voltage protection
• Onboard voltage translator, select 3.3V/5V operating voltage by jumper
• Onboard 120Ω terminal resistor, configured by jumper
• Breakout SPI control pins, for connecting with host control boards like STM32/Arduino
• Comes with development resources and manual (examples in C and Python)
