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

This shield is a two-channel CAN BUS HAT for Raspberry Pi. It supports the CAN FD protocol and supports transmission speed up to 8 Mbps.

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’s transmission rate from 1Mbps to 8Mbps. At the same time, CAN FD improves real-time performance and extends user data frames, providing higher efficiency.

The Seeed 2-Channel CAN-BUS(FD) Shield for Raspberry Pi is based on MCP2517 CAN FD Controller and MCP2557 CAN FD Transceiver which communicates with Raspberry Pi via the high-speed SPI interface. You can power this shield via your Raspberry Pi’s 40 pin header, or you can use the 12 - 24V DC screw terminal to supply the power for the whole system.
