LIN Bus Configuration And Test Environment for Embedded Solutions Such As The Arduino Uno

Posted by Industry News on


LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car. European car manufacturers started using different serial communication topologies, which led to compatibility problems.

In the late 1990s, the LIN Consortium was founded by five automakers (BMW, Volkswagen Group, Audi Group, Volvo Cars, Mercedes-Benz), with the technologies supplied (networking and hardware expertise) from Volcano Automotive Group and Motorola. The first fully implemented version of the new LIN specification (LIN version 1.3) was published in November 2002. In September 2003, version 2.0 was introduced to expand capabilities and make provisions for additional diagnostics features. LIN may be used also over the vehicle's battery power-line with a special DC-LIN transceiver. 

LIN Bus Breakout Board For Embedded Systems

The above shown LIN Bus breakout board connects to the embedded solution, in this case an Arduino Uno. The board comes with a Microchip MCP2004A transceiver, which is compliant with LIN Bus Specifications 1.3, 2.0, and 2.1 and is compliant to SAE J2602. It supports baud rates up to 20 Kbaud with a LIN-compatible output driver.


  • Compliant to SAE J2602
  • Meets LIN-Bus specifications 1.3, 2.0 and 2.1
  • 43 VDC Load dump protection
  • 3.3 VDC or 5 VDC Logic
  • Master or Slave configuration (Select master by closing JP3 )
  • Vbatt input via 2.1mm jack socket or screw terminal


Microchip APGRD004 - Automotive Ambient Lighting Module Reference Design With LIN Bus Interface

The above shown LIN Slave module used for this particular test configuration is a Microchip APGRD004. The APGRD004 is a automotive ambient interior lighting module reference design demonstrates microcontroller based control of RGB LED devices. This module can be controlled remotely by a master body controller via a LIN bus. These modules are offered in a very compact form factor board and comprise of a PIC12F615 MCU, an MCP2021 LIN transceiver/voltage regulator, and RGB LED. LIN commands are interpreted by the module to control color mixing (16,383 colors) and intensity (1023 levels). The kit ships with four modules to assign as lighting zones in a LIN or J2602 network. These modules can also be used in conjunction with the APGDT001 LIN Serial analyzer to quickly create a working LIN network straight out of the box.

Microchip APGDT001 - LIN Serial Analyzer

The Microchip APGDT001 LIN Serial Analyzer development tool enables the user to monitor and communicate to a LIN (Local Interface Network) bus using a Personal Computer (PC). 

This is a powerful tool which can be used to send messages, monitor the bus traffic, perform errors checks and filter messages amongst many other features, allowing the user to develop and debug the system implementation.
