2-Channel Isolated CAN FD Expansion HAT for Raspberry Pi, Multi Protections

2-Channel Isolated CAN FD Expansion HAT For Raspberry Pi, CAN FD Support, Multi Onboard Protection Circuits

2-Channel CAN FD HAT For Raspberry Pi

Multi protections, high anti-interference capability, stable operation

Features At A Glance

The 2-CH CAN FD HAT is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supports CAN FD (CAN with Flexible Data-Rate). It will enable CAN bus for your Raspberry Pi, not only the original CAN 2.0 protocol, but also the CAN FD extension, with higher data throughput.

Thanks to multi onboard protection circuits, including 500W lightningsurge, ESD protection, short circuit protection, and electrical isolation, it make the communication more safe and more reliable.

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
• Supports both traditional CAN2.0 and CAN FD protocols
• Breakout SPI control pins, for connecting with host control boards like STM32/Arduino
• Onboard electrical isolation, up to 5KV isolated voltage, stable operation, higher anti-interference capability
• Onboard lightningproof, ESD protection, short circuit protection, more safe communication
• Onboard voltage translator, select 3.3V/5V operating voltage by jumper
• Onboard 120Ω terminal resistor, configured by jumper
• Comes with development resources and manual (examples for Raspberry Pi/Arduino)
