The ELM327 is a microchip that acts as a bridge between your car’s OBD2 port and your Android device via Bluetooth or Wi-Fi. This combination provides a cost-effective and convenient way to perform car diagnostics right from your phone. You can find excellent resources on this topic on our android obd2 application page.
