DEJA.js Tour & IO
Automate and expand. Leverage structured presets and plug-and-play code to push your layout beyond basic throttle control.
Core Capabilities
🗺️ Guided Presets
Create and execute sequential commands (Tours). Showcase routes, execute demonstrations, and automate complex yard movements with a single tap.
🔌 Plug-and-Play IO
Download provided sketch code for Arduino and Pico W. Expand your layout with hundreds of pins for signals, sensors, and servos without writing backend logic.
💡 Dynamic Effects
Control physical lighting arrays, addressable LEDs, and relay modules directly from the Throttle interface. DEJA handles the protocol translation.
🔄 Protocol Agnostic
Communicate over direct serial USB, local WebSocket, or remote MQTT. Connect microcontrollers exactly how your specific layout geometry demands.
Grows With Your Layout
A command station is only the beginning. True modern layouts require distributed hardware to handle localized tasks like block detection and signal logic.
DEJA.js IO provides a standardized way to pull those localized microcontrollers into a unified software interface, so your layout acts as one cohesive, engineered system.
