The Next Stop Master rides along, tracks the bus over GPS, and syncs the route, timetable and announcement audio from the cloud over 4G. On board, it drives every Next Stop display and announcer speaker wirelessly over ESP-NOW — no cabling, no per-device SIMs, no per-device setup.
Register the master against a bus once. From then on it keeps itself — and every slave on board — up to date.
Pulls the bus name, timetable and full stop list from the BusParrot cloud over 4G — and re-checks on a schedule, so office edits reach the bus the same day.
Reads GPS continuously, works out the upcoming stop from position, direction and time of day — the same proven logic as the standalone Next Stop Display.
Broadcasts ready-to-scroll next-stop text to every display, pushes announcement MP3s to every speaker, and cues the audio as the stop approaches.
Sends live positions to the BusParrot platform over 4G — and optionally over long-range LoRa radio — powering live maps, ETAs and fleet dashboards.
Slaves pair to the master on first power-up and need nothing else — fit as many per bus as you like.
GPS + 4G + LoRa hub. Tracks the bus, syncs the cloud, drives every slave on board. One per bus.

Explore the announcer →A city bus needs the next stop visible and audible everywhere — front, middle, rear, door. Wiring four devices to one GPS is the expensive part. We removed it.
Only the master talks to the internet. Displays and speakers carry no SIM, no Wi-Fi setup, no accounts — they simply listen to their master.
Power a new display or speaker anywhere on the bus and it pairs to the nearest master in seconds. Every unit shows and says the same thing, in step.
Route, timetable and audio live on the master's flash. Coverage drops in the ghat section? Announcements keep running; telemetry catches up later.
Change a route or re-record a stop announcement in the office; flag the bus for sync. The master picks it up on its next check-in and re-seeds every slave.
Optional long-range LoRa uplink sends positions to a depot gateway — handy for terminals, depots and low-coverage rural stretches.
Hold the setup button and the master opens its own Wi-Fi portal — APN, tracking interval, radio settings, all from any phone browser. No app, no laptop.
Same rugged platform as our deployed IoT gateways — with the radio set a bus actually needs.
