Note on live data
The board comes ready to connect to the Seattle Transit Live data service for real-time vehicle positions and firmware updates. Access to this optional service is included in the board price.
Live updates depend on public transit-agency feeds and the continued operation of the Seattle Transit Live service. If live data is interrupted, the board can continue displaying its stored Spring 2026 schedule data for the life of the board.
