)
Product Description
Free Shipping Within the United States!
The PiCAN FD board transforms your Raspberry Pi into an advanced CAN FD node, powered by the Microchip MCP2517FD controller and MCP2562FD transceiver, fully compliant with the ISO 11898‑1:2015 standard. It supports classical CAN at arbitration bit rates up to 1 Mb/s and increases data-phase throughput up to 8 Mb/s, making it ideal for demanding applications in automotive, industrial, and embedded systems.
This version includes an onboard 5 V / 3 A switch-mode power supply, capable of accepting input voltages from 7 V to 24 V. The SMPS provides regulated power to both the PiCAN board and the Raspberry Pi, streamlining system power management and eliminating the need for a separate supply. With built-in reverse-polarity protection and efficient power conversion, the board is well-suited for harsh or remote environments where reliability is critical.
A key feature is the integrated PCF8523 real-time clock with a battery backup, ensuring accurate timekeeping even during power interruptions. This is especially valuable for data logging, message timestamping, and other time-sensitive operations. The board offers both a DB9 connector and a 4-way screw terminal for CAN bus access, along with a jumper-selectable 120 Ω termination resistor and configurable DB9 pinout.
Additional features include an interrupt output on GPIO25 for responsive, event-driven CAN handling, onboard status LEDs for monitoring activity, and footprints for optional serial LCD displays. Four mounting holes follow the Raspberry Pi HAT standard, allowing for easy and secure installation.
Once SPI is enabled in Raspberry Pi OS and the SocketCAN driver is installed, the board is recognized as can0, ready for development using C or Python. Whether you're building next-generation vehicle networks, developing industrial automation systems, or logging high-speed sensor data, this board delivers a complete, powerful, and dependable CAN FD solution.

Integrated Power and CAN FD Connectivity for Demanding Applications
The PiCAN CAN Bus FD Board with Real-Time Clock and SMPS transforms the Raspberry Pi into a complete CAN FD computing platform while eliminating the need for a separate power supply. In addition to high-speed CAN FD communication with data rates up to 8 Mbps and payloads of up to 64 bytes per frame, this version features an onboard 5 V / 3 A Switch-Mode Power Supply (SMPS) that accepts a wide 7 V to 24 V DC input. This allows both the Raspberry Pi and the PiCAN board to be powered from a single industrial or automotive power source, significantly simplifying wiring and improving system reliability. The efficient SMPS includes reverse-polarity protection, making the board particularly well suited for installation in vehicles, industrial control cabinets, and other demanding environments. Combined with the integrated battery-backed real-time clock and Linux SocketCAN support, the board provides a professional platform for robust CAN FD application development.
The integrated power supply makes this version especially attractive for embedded systems that operate from 12 V or 24 V battery systems, where compactness and reliability are critical. Typical applications include vehicle diagnostics, fleet telematics, industrial automation controllers, CAN FD data loggers, robotics, predictive maintenance systems, and intelligent IoT gateways. Developers can leverage the Raspberry Pi’s networking, storage, and processing capabilities while powering the entire system from a single DC source, reducing external components and installation effort. Whether deployed in a vehicle, on a production floor, or as a remote monitoring station, the PiCAN CAN Bus FD Board with SMPS delivers a streamlined, dependable, and high-performance CAN FD solution for professional embedded applications.
