Waveshare 2-Channel Isolated CAN FD Expansion HAT For Raspberry Pi With Dual CAN interfaces, Industrial Isolation - RS2129

Description:

This is a 2-Channel CAN bus expansion HAT designed for Raspberry Pi, supporting CAN FD (CAN with Flexible Data-Rate); the speed is higher than the traditional 1Mbps of CAN2.0, features multiple onboard protection circuits, high anti-interference capability, and stable operation. It is suitable for fields such as automotive devices or industrial automation.

Specifications:

• CAN controller: MCP2518FD
  
• Control bus: SPI 
• Screw terminal input voltage: DC 8~28V
  
• Operating voltage: 5V
  
• Logic level: 3.3V/5V

Features:

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards and 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, and safer 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)
