2-Channel CAN-BUS(FD) Shield for Raspberry Pi

We have released a lot CAN BUS modules, shields, and hats , but the 2-Channel CAN-BUS(FD) Shield for Raspberry Pi is unique: it supports CAN FD! CAN FD(CAN with Flexible Data-Rate) protocol is an upgraded version of the traditional CAN BUS that increases the CAN max transmission rate from 1M to 8M. At the same time, CAN FD improves real-time performance and extends user data frames.

The Seeed 2-Channel CAN-BUS(FD) Shield for Raspberry Pi is based on MCP2517 CAN FD Controller and MCP2557 CAN FD Transceiver, and it communicates with Raspberry Pi via the high speed SPI interface. You can power this shield with Raspberry Pi via the 40 Pin Header or you can use the 12 ~ 24V DC screw terminal to supply the power for the whole system. High-quality Panasonic capacitors and TI power chips, reasonable circuit design to build a stable power management system, which provides stable 3.3V and 5V power supply for all parts of the system, to ensure the stability of communication.

We know that the devices at both ends of the CAN BUS need to add a 120Ω terminating resistor to avoid reflection. With the help of an onboard 120Ω resistor and its enable switch, you can easily choose whether you need to connect a 120Ω resistor. Besides we provide two Grove I2C connector for you, in case you need to work with more Grove modules.
