Signal Boards are in stock with limited supply, more coming soon.
The Signal Board has 24 independent LED outputs and plugs in the Expansion Port of the QuadLN_S. Any mix of Common Cathode, Common Anode and 2-Lead Bicolor LEDs can be used. Each LED output signal is available on a standard 3-pin header which also provides 5V and Ground which makes wiring easy using servo extension cables.
Special features including very cool Searchlight transition effects, CPL semaphore effect, and realistic fade are built-in. Flashing aspects are handled by the QuadLN_S with proper flash rates, eliminating Loconet traffic jams when trying to have JMRI constantly flash signals. A proper flash rate is available for Grade crossings along with cross fade that makes your crossing look like the prototype back when bulbs were used.
Software brightness adjustment is provided for each LED output plus each output has a built-in 330 ohm resistor eliminating the need for an external resistor in many cases. If you are driving 2 LEDs in series and need a lower resistance, there are on-board mounting points to add your own resistors.
Up to 48 signal aspects can be defined to provide prototypical signaling. Each aspect can control up to 4 LEDs. Aspect control is very flexible and each aspect can be configured for control by Signal Mast messages, Turnout messages or Sensor messages. The QuadLN_S Signals Manual has all the details!
