Documentation

LN Quad Detector

A variation on IO4-QuadOD that replaces the WemosD1 & IO4 connections with an Arduino Pro Mini and LocoNet-style communications.

This simple 4-pack module should end up with a BOM cost between $5 and $10, so a full stand alone quad detector pack would run about $60 with detector boards.

The MRRWA Embedded Loconet library includes support for LN-SV V2 configuration management, which is also supported by JMRI; it should be pretty easy to write an addressable Detector sketch (TBD) with assorted XML definitions suitable for DecoderPro3…
