Description
An L-shaped 21MTC adapter board (in the style of the Märklin® 6090x) that additionally breaks out AUX3 and AUX4 function outputs for LokSound 5 and LokPilot 5 decoders. The L form factor fits models where a straight board won't, and the extra outputs unlock more lighting and special functions.
A flexible mounting and expansion option for detailed 21MTC installs.
- Interface: 21MTC, L-shaped board
- Adds: AUX3 + AUX4 outputs
- For: LokSound 5 / LokPilot 5
