The PiCAN FD Duo board provides two-channel CAN-Bus FD capability for the Raspberry Pi. It uses the Microchip MCP2517FD CAN controller with MCP2562FD CAN transceiver. The connection is made via a 4-way screw terminal. A real-time clock with battery backup (battery not included) is also on the board.
The board also comes with a 5 VDC 1A SMPS that powers the Raspberry Pi via the screw terminal. The Switch mode power supply (SMPS) allows connecting an input voltage range of 6 VDC to 20 VDC suitable for industrial and automotive applications and environments.
The advanced CAN FD bitrate extends the data section's length to up to 64 bytes per frame and a data rate of up to 8 Mbps.
Raspberry Pi 4 Compatibility
The SMPS version of the PiCAN board is currently not suitable for the new Raspberry Pi 4 Model B. The RPi 4 requires a 5VDC@3Amp power supply, while the SMPS supplies only 1 Amp.

CAN Bus Screw Terminals
The CAN Bus connection is accomplished via the 4-way screw terminals:
There are two 120 Ohm termination resistors fitted to the board. To use the terminator solder a 2-way header pin to JP1 and JP2, then insert a jumper.
Furthermore, there is a red LED fitted to each channel; they are connected to the Raspberry Pi's GPIO04 and GPIO26.
