UTOPIA: an open-source round-screen driving gauge
An independent project for ESP32-S3 touch displays that brings vehicle data, GPS lap timing, G-force, and other driving information onto configurable in-car gauges.
- For
- DIY drivers building custom in-car gauges
- Worth noticing
- ESP-NOW supports one main gauge and up to four secondary displays; the project cautions that listed vehicle configurations are not proof of real-car compatibility.
Field notes
The project describes an ESP32-S3 gauge with a 1.85-inch round touch screen and wireless coordination for as many as five displays. Its feature list includes vehicle readings, GPS lap timing, G-force and tire-pressure data, with some inputs shared from the module that collects them. The homepage reports 40 built-in vehicle configurations but explicitly says that count does not establish real-world compatibility; broader vehicle and wireless testing is still in progress.
