PiCAN2 Duo Isolated CAN-Bus Board for Raspberry Pi

Due to global shortage of electronic components, we are currently unable to take new orders. Please see alternative product below.
Usually ships within 1 business day.

Product Description

Please consider the alternative: 

This PiCAN2 DUO ISO board provides two independent isolated CAN-Bus channels for the Raspberry Pi. It uses the Microchip MCP2515 CAN controller in combination with the Texas Instruments ISO1050 isolated CAN transceiver. Connections are made via 4 way screw terminal plugs.
There is an easy-to-install SocketCAN driver, and programming can be accomplished in C or Python.

Raspberry Pi 4 Compatibility

The PiCAN board is fully compatible with the new Raspberry Pi 4 Model B.


  • Two galvanically isolated CAN Bus channels
  • 70 mA 5 VDC output per channel that can be use to power other CAN Bus nodes
  • CAN Bus v2.0B at up to 1 Mb/s
  • High speed SPI Interface (10 MHz)
  • Standard and extended data and remote frames
  • CAN Bus connection screw terminal
  • 120 Ohm terminator ready
  • Four fixing holes, in compliance with Pi HAT standard
  • SocketCAN driver, appears as can0 and can1 to application
  • Interrupt RX on GPIO25 and GPIO24

Galvanic Isolation

High noise levels on a CAN bus network have the potential to destroy CAN bus transceivers. This noise originates mainly from two sources, ground loops and electrical line surges. Protecting a network against this destructive energy requires the galvanic isolation of the CAN bus system from other local node circuitry.
