The MACH-ETH is an automotive network interface that features one Ethernet port, two CAN FD channels, a LIN channel, a USB and RS-232 port, and multiple I/Os. The device can act as an Ethernet-CAN(/FD), Ethernet-LIN, USB-CAN(/FD) and USB-LIN interface as well as CAN(/FD)-LIN gateway, and a user-scripting feature allows to run user applications directly on the device. The open communication protocol enables access to CAN(/FD) and LIN channels over Ethernet or USB, and to transmit/receive frames.

The communication protocol over Ethernet or USB enables access to CAN(/FD) and LIN bus channels over Ethernet or virtual COM port respectively.

A user-scripting feature, which allows to run user applications directly on the MCU, can be used for HiL testing and rest-bus simulations. The device can act as an interface, a gateway, or bridge between all its channels.

An analogue input and a digital output enable the user to interact with external peripherals.


  • 10/100 Ethernet port
  • 2 CAN-HS channels with CAN FD support

  • RS-232
  • Analogue input and digital output
  • 4 DIP switches
  • 10 status LEDs
  • Open communication protocol for integration over Ethernet and USB
  • User-programmable
  • Externally or USB-powered

Usage Examples

  • ETH-CAN(/FD) and ETH-LIN interface
  • CAN(/FD) – LIN gateway
  • CAN – CAN-FD gateway
  • Remaining bus simulations
  • User-programmable HiL simulations


The open communication protocol (API) allows to easily access CAN(/FD) and LIN channels over Ethernet (supports both TCP and UDP) or USB VCP. With the help of the communication protocol, the user can configure the device’s CAN/CAN FD/LIN channels and frames can be transmitted and received.

User Programming

The device firmware can also be fully customizable in C language. An open-source SDK, which shows the use of all the peripherals, is available on GitHub. A user application can be uploaded into the device over web bootloader or USB. It is also possible to debug the application directly on the target (STM32 SWD).

  • Firmware customizable in C/C++
  • Free-of-charge C language SDK
  • Free-of-charge IDE and C/C++ compiler
  • Firmware update over USB, Ethernet or ICSP
