This is the Layout Control Bipolar Turnout Card identified in the Layout Control Mother Board Design for the MRNet project.

MRNet -- Layout Control Bipolar Turnout Card

Introduction

The purpose of the layout control bipolar turnout card is to provide an easy way to control up to 8 bipolar turnouts.

The layout control LED card is in the schematic below:

The layout control bipolar turnout card has been layed out. The following files are available:

Bipolar Turnout Card PCB Artwork Layer: This contains the artwork layer that specifies where the components are to be placed.
Bipolar Turnout Card PCB Back Layer: This is the back (solder) side of the board.
Bipolar Turnout Card PCB Front Layer: This is the front (component) side of the board.
Bipolar Turnout Card PCB Excellon Drill File: This is the drill file for the PCB in industry standard Excellon format.
Bipolar Turnout Card PCB RS-274X Back Layer: This is the industry standard RS-274X file that specifies the apertures and line placement for the back layer.
Bipolar Turnout Card PCB RS-274X Front Layer: This is the industry standard RS-274X file that specifies the apertures and line placement for the front layer.
Bipolar Turnout Card PCB Drill Size File: This is a short file that specifies the drill sizes for the Excellon drill file.
Bipolar Turnout Card PCB Parts List File: This is the parts list file.
Bipolar Turnout Card PCB Size and Hole Count File: This is a short file that specifies the board size in inches and the total number of holes.
