2-Channel CAN-BUS(FD) Shield for Raspberry Pi (MCP2518FD) is unique: it supports CAN FD½ 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.

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.  To ensure the stability of communication, we’ve used high-quality Panasonic capacitors and TI power chips, along with quality circuit design, to build a stable power management system, which provides stable 3.3V and 5V power supply for all parts of the system.

Attention

You can see that Seeed Studio used nylon columns during assembly to avoid short-circuiting between the metal terminals under the CAN BUS port and the HDMI interface on the Raspberry Pi. So please be sure to assemble the nylon column as shown.
