The PCAN-Gateway series from PEAK System supports the transmission of CAN Bus data frames over IP networks. The PCAN-Ethernet Gateway FD DR supports CAN FD in addition to the Classical CAN Bus Standard.

Both CAN Bus interfaces are CAN FD compliant with data bit-rates of up to 10 Mbit/s. An AM5716 Sitara processor provides the required performance for the CAN Bus and Ethernet port. In cases where a CAN network utilizes a PCAN-Ethernet Gateway FD DR, the LAN interface is fully capable of accessing the CAN network with one or more computers. A conventional CAN Bus interface is not required. An application with two gateways allows the connection of separate CAN Bus networks via an IP network, thus eliminating the restriction that comes with the maximum physical CAN Bus length.

A standard Internet router allows the configuration of the products via a web interface, including status information and communication settings, message forwarding, and filters. Alternatively, a JSON interface provides access via software.

Teensy 4.1 Triple CAN Bus Board with 240x240 LCD and Ethernet

This is a Teensy 4.1 board with triple CAN connections, two CAN 2.0B and one CAN FD, and ethernet magjack. It can be powered by an external +12 VDC with reverse voltage protection. Included is also a 240x240 wide angle IPS TFT LCD display.

The Teensy 4.1 is an Arduino-compatible board with an Arm Cortex-M7 microcontroller running at 600 MHz. The board is compatible with the Arduino IDE and the Arduino library. In most cases, code written for another Arduino board works with a minimum of changes on a Teensy. As the name implies, the board is tiny. For example, the current form factor is only about 18 by 36 millimeters. However, do not let the size mislead you; these boards pack a ton of functionality. For example, the new Teensy 4.1 features a megabyte of RAM, two megabytes of Flash, a bevy of I/O options, cryptographic support, a hardware floating-point processor (FPU), and a built-in real-time clock (RTC).
