Introduction
The Back-plane Experimental Electronics Framework (BEEF), is an electronic development environment for Machine Interfacing and in some cases Control.
The framework is based around a passive IO back-plane into which interface, control, power and driver cards can be plugged. These plugin cards will be a selection that best suits the RepStrap/RepRap that you want to create.
The framework actively supports prototyping and experimentation through provided designs for Break-out and Prototyping cards.
Custom designed cards may also be mixed and matched to suit your needs.
The need for a framework that enables a variety of solutions has grown from the way thet the Reprap Project has embraced a range of machine designs and control solutions. Not only from a technological point of view but also from the point of view of the inteded recipient of the technological benefit.
A common framework was needed that could deliver a range of solutions ranging from the Controler and Firmware free. Through to Controled and firmware rich solutions. Using a range of Microcontroler, Programmable Logic and Actuator solutions. Optional methods of supplying power to the electronics and machinery are needed also
The core set of Schematic and PCB designs have been optimised where ever possible to facilitate "Kitchen Table" level DIY. In many cases this will be simple single sided designs using commonly (And internationaly) available, standard, 2.54mm pitch, pin and socket PCB connectors.
The PCB designs may also be sent out to local PCB production companies for those that would prefer this route.
Guidance Notes
Whilst the Prototyping and Break-out designs have many pads and allow all backplane connections to be brought onto the card best advice is to drill holes etc as needed and only solder on the backplane plug pins that are needed.
Boards and Functions
Quick Start Files
For those less interested in the development but more in using the designs. These files are a quick way to get started using the results of the BEEF development work.
The Electronic Experimenters Back-plane
- A single sided 5 card design using 64 way 2.54mm PCB connection sockets arranged as two columns by 32 rows.
- Back-plane Schematic
- Back-plane PCB Design
A simple plug-in break out board.
- A single sided design using a right angled 64 dula row plug strip, featuring pads suitable for 2.54mm pitch screw terminals & soldered wire connections.

These Files are Mirrored
These files are mirrored in: http://dev.forums.reprap.org/read.php?13,33975 and the Official Repository along with the Library. This is part of the Hall of Mirrors Problem and the Other Spaces Problem. Yes, this is a Library problem, which we will have to figure out.
