Raspberry Pi 2-CH CAN FD HAT expansion board (17075)

TheRaspberry Pi 2-CH CAN FD HAT Expansion Board (17075 ) is a high performance expansion board (HAT) for the Raspberry Pi that allows you to connect and operate with a CAN interface. It supports CAN FD (CAN with Flexible Data Rate), which enables data transfer not only with the original CAN 2.0 protocol, but also CAN FD with higher data throughput. CAN FD stands for Controller Area Network Flexible Data-Rate. CAN FD is an enhanced version of the CAN protocol that allows for higher data rates and more information.

With many built-in protection circuits, including 500W lightning surge, ESD protection, short circuit protection, and electrical isolation, it makes communication safer and more reliable.

Compatible with Raspberry Pi: This expansion board is specially designed for use with Raspberry Pi, allowing it to be easily connected to the GPIO output connectors on the Raspberry Pi.

This product is a useful addition to the Raspberry Pi for projects that require communication with devices or systems that use the CAN protocol.

Main features:

• Has a standard Raspberry Pi 40PIN GPIO expansion connector, supports Raspberry Pi series boards, Jetson Nano
• Supports both traditional CAN2.0 and CAN FD protocols
• Features SPI control pins for connection to host control boards such as STM32/Arduino
• Built-in electrical isolation (isolated voltage up to 5kV) ensures stable operation, higher ability to prevent interference
• Has built-in lightning protection, electrostatic discharge protection, short circuit protection, more secure communication
• Has a built-in voltage converter (working voltage is selectable 3.3V/5V by jumper)
• Has a built-in 120 ohm termination resistor (configurable with a jumper)
• Comes with development resources and a manual (examples for Raspberry Pi/Arduino)
