ESU 51998 21-Pin MTC to Next18 Adapter Board
This small adapter board is a practical tool for equipping some models (e.g., from Liliput) with a LokSound decoder: While these models have a 21MTC interface, the required length for a LokSound 5 decoder was not taken into account. With this adapter board, a LokSound 5 Micro can be installed horizontally in the available space provided there is a width of 21.5mm.
Dimensions with LokSound 5 Micro 58818 installed: Overall width 21.5mm x 19mm length.
