About the Signal panelized X4 PCB
Signal panelized X4 is an open source PCB design by slonket, published on GitHub under the MIT license. It is a 2-layer board measuring 47.8 × 79.8 mm, with 6 components from 2 distinct parts.
By type, the board carries 4 resistors and 2 diodes.
From the project
An assortment of projects to supplement the Lego 12V "Gray" era trains.
The majority of 12V gray-era sets are inspired by the Deutsche Bundesbahn (DB); even the turnouts feature a "lantern" brick akin to those on German turnouts. The 12V signal brick (70022), however, does not hold a connection to a real German counterpart. This project reimagines the Lego signal head as two different German Hp signals ("home" and "entry") while maintaining the original's blocky charm.
