This adapter board can be docked to all decoders with a Next18 connection and offers a PluX12 interface on the locomotive side. In particular, TT locomotives from Tillig can now be easily converted with our LokSound 5 micro Next18 or LokPilot 5 micro Next18. The flex circuit board can be folded and extended to almost any length. The adapter board comes with shrink tubing and speaker connection cables.
