The 2-CH CAN HAT+ is a two-channel CAN bus (Classical CAN) expansion HAT designed for the Raspberry Pi. It supports expanding multiple CAN channels by stacking with the 2-CH CAN HAT or 2-CH CAN FD HAT. Adopting the HAT+ standard design, it is compatible with the Raspberry Pi series boards, including Raspberry Pi 5, 4, 3, and Zero. Several onboard protection circuits, including electrical isolation, enhance communication safety and reliability. It supports a wide voltage input range of 7-36V, making it suitable for industrial applications.
Features
- Standard Raspberry Pi 40PIN GPIO extension header supports Raspberry Pi series boards / Jetson Nano.
- Adopts the MCP2515 and SN65HVD230 dual chips combined solution, allowing 2-channel CAN communication.
- Onboard unibody power supply isolation, providing stable isolated voltage, requires no extra power supply for the isolated terminal.
- The onboard digital isolator and signal isolation make communication safer and stable, with better protection against electrical interference.
- The onboard external power supply terminal supports 7~36V broad voltage power input supports powering the Pi and the HAT at the same time.
- The onboard SM24CANB TVS (Transient Voltage Suppressor) diode provides ESD 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 connect with other host control boards.
- Comes with online development resources and a manual (examples in Python/C).

Raspberry Pi Cookbook: Software and Hardware Problems and Solutions
With millions of new users and various new models, the Raspberry Pi ecosystem continues to expand, along with further questions about the Pi’s capabilities.
The third edition of this popular cookbook provides more than 200 hands-on recipes that show you how to operate this miniature low-cost computer with embedded Linux; program it with Python; hook it up to sensors, motors, and Arduino boards; and even use it with the internet of things (IoT).
Prolific hacker and author Simon Monk also teaches the fundamental principles to support your use of new technologies with the Raspberry Pi.
This cookbook is ideal for programmers and hobbyists familiar with the Pi through resources such as Getting Started with Raspberry Pi (O’Reilly). Code examples from the book are available on GitHub.
