Open-source wireless for FPV racing

Light up the whole track.
Without the wires.

RaceLink puts every LED, every start block and every sensor on one synced wireless link — so your event looks as fast as it flies.

Built for the places ordinary wireless gives up: WiFi, Bluetooth and ESP-NOW run out of range and reliability long before a proper LoRa link does — across a noisy field, full of pilots, all day long.

What you get

Everything on the track, in perfect sync

No more cable runs across the field. RaceLink does the heavy lifting over the air — and it never gets in the way of flying.

Synced light shows

Every node runs off one shared wireless clock. Waves, cascades and full-track effects all fire perfectly in time.

Start blocks that talk

Show the channel and pilot name right on the start block's e-paper display — readable in full sun.

Live telemetry

Battery level and signal strength of every device, live in your browser — spot a flat node before it dies on track.

Stays off your frequencies

Runs on 433 / 868 / 915 MHz radio. It never touches your 2.4 GHz control link or 5.8 GHz video.

Long range, rock solid

Modern LoRa modems reach across the whole site and keep working in the noisiest RF environments.

Built to be bent

Fully open source. Use it standalone, plug it into RotorHazard, or build your own device classes and effects.

How it fits together

Three pieces, one link

The host runs the show, the USB gateway turns your commands into radio, and your nodes light up. That's the whole system.

No computer at the event? Headless mode skips the host and gateway entirely — one node takes over both roles and remote-controls up to 40 devices from a single button. See how the system works →

Up and running

From box to light show in four steps

01

Flash the firmware

Grab a ready-made firmware file and write it once. After that, updates go over the air.

02

Plug in & open

Connect the USB gateway to a laptop or Raspberry Pi and open the WebUI.

03

Pair & group

Discover your devices and drop them into groups like Start Line or Pit Wall.

04

Build a scene & run

Assemble a playlist of effects, press Run, and watch the track come alive.
