The A0 is the latest in Macchina's line of OBD-II interfaces. The A0 uses the power of the ESP32 BLE and WiFi module to allow for wireless access to the OBD-II port most modern cars have.
The Macchina A0 module plugs directly into the OBD-II port found in most modern cars and receives its power from the port. From there, one can interface with the device through a few different methods. The easiest is with software such as SavvyCAN, and Torque Lite on Android. Besides getting all onboard diagnostic information, you're able to control certain aspects of the car and create cool projects such as dash-mounted, and shift lights. The A0 can also be programmed in the Arduino IDE, so there are plenty of possibilities to customise the device for what you want to do with your car!
Features
ODB-II compatibility with all modern cars (1996 or newer)
