SYSTEM ARCHITECTURE

Four Steps.
Fully Automated.

From hardware on the kart to the dashboard command — the system is designed to be invisible until you need it.

01

RF Module on Each Kart

Compact 2.4GHz transceiver mounts under kart fairing, connects to throttle ECU. Fits any kart — electric or petrol. Installs in under 20 minutes per chassis.

02

Trackside Base Station

1–2 base stations cover a full track layout. Connected to RacerFLOW server over LAN — no internet required for safety commands. Full coverage up to 500m per unit.

03

Dashboard Control

Per-kart and global flag buttons in the RacerFLOW dashboard. One click. Under 300ms to kart response. Works on any device — PC, tablet, or smartphone.

04

Incident Auto-Log

Every safety command timestamped and stored automatically. Full audit trail for incident review, insurance documentation, and compliance. Nothing is manual.

Hardware failsafe: If RF signal is lost for any reason, the kart automatically cuts throttle. No command required. Safety is physical, not just software.
