A buddy of mine wants insight into how his vehicle is performing as he drives. He sent me a ArduinoDev ODB-II interface (model B) and said "figure it out". So here we go! We will be exploring the onboard features in future posts, and hopefully some of the options available for this interface.
Let's start with what's included:
Directly pluggable into vehicle’s OBD-II port
Serial data interface (UART or I2C)
Regulated DC 5V output (300mA for model A, 1A for model B, powers the Arduino)
