SeeedStudio 2-channel CAN-Bus HAT for Raspberry Pi
The 2-Channel CAN-BUS(FD) Shield for Raspberry Pi is distinct from other CAN Bus modules, hats or shields for the reason that it also 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 1 Mbps to 8 Mbps. At the same time, CAN FD has the advantage of improving real-time performance and extending user data frames, which provides higher efficiency.
You can power this shield via your Raspberry Pi’s 40 pin header, or you can use the 12 - 24 V DC screw terminal to supply the power for the whole system.
High-quality Panasonic capacitors and TI power chips make sure that the communication stays stable and quality circuit design builds a stable power management system, which provides stable 3.3 V and 5 V power supply for all parts of the system.
The devices at both ends of the CAN BUS need a 120 Ω terminating resistor to avoid reflection, which is solved With the help of an onboard 120 Ω resistor and its switch, with which you can turn the onboard resistor on and off.
