OBD Gauge Cluster
FirmwarePut live engine gauges on a separate dash screen
OBD Gauge Cluster turns a CrowPanel display into a dashboard that reads your car through a BLE OBD-II adapter. It shows standard engine readings, adds manufacturer-specific readings for supported profiles, and saves a CSV log to microSD once a second. Fuel-economy displays depend on the profile and the data the car supplies.
You need the CrowPanel Advance 3.5-inch ESP32-S3 display, a rotary knob and a supported BLE adapter plugged into the car’s OBD-II port. The display uses USB power and a cable to the knob, with no splice into the car’s wiring; normal firmware only reads diagnostic data and can be removed by unplugging it. Vgate iCar Pro BLE 4.0 and vLinker MS are validated, while generic BLE clones remain untested and OBDLink adapters are unsupported.
