From the project

Dual buffered 1:3 multiples with bipolar signal indicator lights.

This is an open hardware project. The repository contains all design files as well as gerbers to order PCBs directly from a manufacturer like PCBWay.com, who kindly supplied prototyping boards for the development of this module.

Upload the .zip in the gerberfiles/` folder to your PCB manufacturer's website to order.

An interactive html BOM is available in the bom/ folder inside of the KiCad project. Just open it in a browser and tick off sourced/placed components. Also shows where on the board components should be placed.
