What hardware do I need to use OBDAI?

You need an OBD-II adapter that plugs into your vehicle’s diagnostic port. OBDAI officially supports Gen 1 and Gen 2 hardware, available at obdai.app/shop. These are tested for reliable connections across all platforms. OBDAI may work with other ELM327-based adapters, but we can’t guarantee compatibility or provide support for third-party hardware.
