Further Shipment Information & Options...

Our Raspberry Pi 3 System With CAN Bus Interface (PiCAN2) comes with a pre-installed Raspbian operating system.

The system is equipped with a PiCAN2 board, depending on the selected option, with or without SMPS (Switch Mode Power Supply). The SMPS allows the powering of the whole system, i.e. the Raspberry Pi and the PiCAN board, per external power connection (e.g. the 12 VDC supply in a vehicle).

System Features

Raspberry Pi 3, Model B+, 1 GB RAM.
Raspberry Pi 16GB Preloaded (NOOBS) SD Card.
PiCAN2 - CAN Bus Interface for Raspberry Pi.
Option: 5VDC 1A SMPS (Switch Mode Power Supply) to power Raspberry Pi and accessories from screw terminal

Reverse polarity protection
High efficiency switch mode design
6 VDC to 20 VDC input range

Power supply adapter is not included

Raspberry Pi 3 Model B+

1.4GHz 64-bit quad-core ARMv8 CPU
802.11n Wireless LAN
Bluetooth 4.1
Bluetooth Low Energy (BLE)
1GB RAM
4 USB ports
40 GPIO pins
Full HDMI port
Ethernet port
Combined 3.5mm audio jack and composite video
Camera interface (CSI)
Display interface (DSI)
PoE HAT support
Micro SD card slot (now push-pull rather than push-push)
VideoCore IV 3D graphics core

The Raspberry Pi 3 B+ is equipped with a high-performance heatsink set to reduce chip hot-spots and to increase the thermal dissipation surface area.

The included PiCAN2 board provides Controller Area Network (CAN) Bus capabilities for the Raspberry Pi.

It uses the Microchip MCP2515 CAN controller with MCP2551 CAN transceiver. Connection are made via DB9 or 3-way screw terminal.

There is an easy-to-install SocketCAN driver, and programming can be accomplished in C or Python.

The Switch mode power supply (SMPS) option allows connecting an input voltage range of 6 VDC to 30 VDC suitable for industrial and automotive applications and environments.

PiCAN2 Features

CAN v2.0 A/B at 1 Mb/s
High speed SPI Interface (10 MHz)
Standard and extended data and remote frames
CAN connection via standard 9-way sub-D connector or screw terminal
Compatible with OBDII cable
Solder bridge to set different configuration for DB9 connector
120Ω termination resistor
Serial LCD ready
LED indicator
Foot print for two mini push buttons
Four fixing holes, comply with Pi Hat standard
SocketCAN driver, appears as can0 to application
Interrupt RX on GPIO25

Important to know!

Per default, the PiCAN2 board comes with the termination resistor activated by means of a jumper.
In case you plan to use the DB9 CAN connector, please be aware that you need to solder jumpers on the board to configure its operation as OBD-II or Standard CAN.
