Editorial interest 78/100 Selection signal · not a rating of the site

A firmware project that turns an ESP32 CYD display into a car dashboard for OBD2 engine data, optional GPS, and trip logging.

Landing page captured for the 2026-11-05 issue.

For: ESP32 CYD owners building an in-car display
Worth noticing: The page lists ELM327 versions 1.5 and 2.1 as tested; other adapter versions are explicitly untested.

Field notes

The described setup pairs an ESP32 CYD display with a Bluetooth ELM327 adapter, while GPS tracking depends on adding a separate module. The page names GY-NEO-6M and GY-NEO-M8N as GPS options and says route history is saved automatically. Its listed functions also include alerts for low battery or high coolant temperature and reading or clearing standard ECU fault codes.
