This expansion board can easily expand your LokPilot V4.0 or LokSound V4.0 decoder (with 21MTC interface!): Benefit from 4 additional function outputs (AUX5 through AUX8) for lighting effects, coupler etc or connect 2 RC-servos! The highlight of the expansion board is the control electronics for synchronised smoke units, just install an ESU smoke unit to generate synchronised steam chuffs or Diesel smoke.
The board measures 15.5mmx 30mmx 5.5mm (0.61 x 1.18 x 0.22 inch)
The module can be directly plugged into a 21MTC interface of a loco (if enough height available) .
