What is the ESP32 Serial OBD2 Gauge Catalyst?

It's an open-source DIY project that lets you build a custom ESP32-based gauge to monitor real-time vehicle data, such as engine status and sensor readings, directly from your car's OBD2 port.

What kind of vehicle data can this gauge display?

It displays live information including engine RPM, vehicle speed, various temperatures, and other sensor readings compatible with the ELM327 interface standards.

Is programming knowledge required to use this system?

No, basic setup using pre-built firmware does not require programming knowledge. For customization or advanced modifications, familiarity with Arduino IDE or PlatformIO is helpful.

What hardware components are needed to build this custom gauge?

You will need an ESP32 development board, an OBD2 to serial adapter cable, a small TFT display compatible with LovyanGFX, and basic wiring components.
