Gauges
Two screens, one language.
Both read the car over CAN, both are configured from the phone over Bluetooth, and both update over the air. What differs is the glass.
Gauge screen mini
A round 466 × 466 AMOLED. Swipe across the glass to change face, or pick one from the app. Faces cover oil pressure, fuel, water temperature, tyre pressures and lap timing, alongside photographic faces drawn at native resolution so nothing is scaled.
Warning limits are yours per signal: set a window and the dial shades the band, the needle colours when it leaves, and an outer ring spins to catch your eye. Day and night themes switch the whole face, and panel brightness is a single setting on the gauge.
| Display | 466 × 466 round AMOLED, capacitive touch |
|---|---|
| Input | CAN bus, listen-only |
| Configuration | Bluetooth LE, from the BlueFrog app |
| Firmware updates | Over the air, verified before it boots |
| Audio | Onboard codec and speaker for alerts |
Gauge screen pico
A compact 172 × 320 bar screen for the places a round dial will not go — a pillar, a console edge, a gap in the dash. It ships on either of two chips, and the app knows which one it is talking to, so an update never crosses them.
| Display | 172 × 320 IPS |
|---|---|
| Variants | ESP32-S3 and ESP32-C6 |
| Input | CAN bus, listen-only |
| Mounting | Rotatable — the screen follows how it is fitted |
Listen-only, always
Neither gauge transmits. Both hang off the bus as pure observers, so adding one to a car cannot disturb anything already on the wire. A gauge that hears nothing says so plainly rather than holding the last reading it saw.
