The 2-CH CAN FD HAT is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supporting CAN FD (CAN with Flexible Data-Rate). It enables CAN bus functionality on your Raspberry Pi, compatible with both the original CAN 2.0 protocol and the CAN FD extension, providing higher data throughput. Equipped with multiple onboard protection circuits, including 500W lightning surge protection, ESD protection, short circuit protection, and electrical isolation, it ensures safer and more reliable communication. Features a standard Raspberry Pi 40-pin GPIO extension header, compatible with Raspberry Pi series boards and Jetson Nano. Supports both traditional CAN 2.0 and CAN FD protocols. Breaks out SPI control pins for connection to host control boards such as STM32 or Arduino. Onboard electrical isolation supports up to 5 kV, ensuring stable operation and improved anti-interference capability. Includes onboard lightning protection, ESD protection, and short circuit protection for enhanced safety. Onboard voltage translator allows selection of 3.3V or 5V operating voltage via jumper. Includes 120 terminal resistor configurable via jumper. Color: blue. Material: plastic. The actual product may have slight color variations, which do not affect performance.
