Agile

Prototype

GPS lap timer and driver display for circuit racing

Agile times laps and micro-sectors from dual-band GNSS, with a live delta against the best clean lap on the driver's display. It records the track outline and the pit lane, fuel bay and pit exit zones, so pitted laps never become the reference. Pit board messages and race-control flags sent from the pit wall appear on the dash. The v1.0 prototype is housed in a 3D-printed development enclosure.

Prototype pre-release for track tests.
