As shipped, the OBD Development Board is a fully functioning OBD-II to USB interface that supports all OBD-II protocols and works with any ELM327-compatible software.
The OBD Development Board features UART and USB interfaces, an OBD breakout with access to all all 16 J1962 (OBD port) pins, three module slots with breakout headers, and a number of configuration jumpers and test points. Full details are available in the ‘Schematics’ section below.
The unique modular design offers considerable flexibility, allowing engineers to quickly evaluate, prototype, and verify the major circuit blocks.
Shown with optional ECUsim 2000 and laptop (not included). For more information see the Lab Manual.
