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

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

Expansion HAT Features

• Based on Raspberry Pi design, suitable for Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B.
• Support external wide voltage of 8~28V to supply power to Raspberry Pi and 2-CH CAN FD HAT at the same time or directly supply power to 2-CH CAN FD HAT from Raspberry Pi.
• Support CAN FD, the data baud rate breaks through the 1Mbps limit of traditional CAN2.0.
• Reserved control interface for easy control by other controllers whose logic voltage is 3.3V/5V.
• CAN bus adopts electrical isolation, the isolation voltage can reach 5 kV.
• Multiple protection devices onboard, with short-circuit protection, electrostatic protection, effective suppression of lightning and ESD, each channel provides 500W lightning surge protection.
• The interface has a 120Ω terminal resistance, which can be switched by jumper caps.
• The working mode of dual-channel CAN can be configured, that is, two channels share a set of SPI or two channels use two independent SPIs respectively.
• Provide complete supporting information manuals and demos.
