2-Channel Isolated CAN Bus HAT+ for Raspberry Pi

Waveshare 27338 - 2-Channel Isolated CAN Bus Expansion HAT For Raspberry Pi, Dual Chips Solution, Stackable Design For Expanding Multiple CAN Channels, Built-In Multi Protections, Raspberry Pi HAT

Features

The 2-CH CAN HAT+ is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi. Supports expanding multiple CAN channels by stacking with the 2-CH CAN HAT or 2-CH CAN FD HAT. Adopts HAT+ standard design, compatible with Raspberry Pi series boards such as Raspberry Pi 5/4/3/Zero. Onboard various protection circuits, including electrical isolation to make communication more safe and reliable. Supports wide range voltage input of 7~36V, suitable for industrial applications.

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards / Jetson Nano
• Adopts MCP2515 and SN65HVD230 dual chips combined solution, allows 2-channel CAN communication
• Onboard unibody power supply isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal
• Onboard digital isolator, signal isolation makes the communication more safe and stable, and better anti-interference
• Onboard external power supply terminal, supports 7~36V wide voltage power input, supports powering the Pi and the HAT at the same time
• Onboard SM24CANB 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 and I2C control pins, for connecting with other host control boards
• Comes with online development resources and manual (examples in Python/C)
