The 2-Channel CAN FD Raspberry Pi HAT by Waveshare is a robust Raspberry Pi expansion board designed to seamlessly integrate advanced CAN bus communication into your Raspberry Pi projects.
This HAT empowers your Raspberry Pi or Jetson Nano with two independent channels supporting both the classic CAN 2.0 protocol and the newer CAN FD (CAN with Flexible Data-Rate) standard, which allows for significantly higher data throughput than its predecessor.
This makes it an excellent choice for demanding applications in fields like automotive diagnostics, industrial control systems, and any scenario requiring reliable, high-speed data exchange over a CAN network.
Engineered for safety and reliability, this Waveshare CAN FD HAT incorporates a comprehensive suite of onboard protection circuits. These include up to 5KV electrical isolation between the CAN bus and the Raspberry Pi, 500W lightning surge suppression, robust ESD protection, and short circuit safeguards on each channel.
The CAN FD Raspberry Pi development board also offers great flexibility with breakout SPI control pins for connection to other microcontrollers like STM32 or Arduino, selectable 3.3V/5V logic levels, and switchable 120? terminal resistors. This ensures stable operation and high anti-interference capability, making it a dependable solution for your CAN communication needs.
