After RaspberryPI foundation released the Pin outs for the main connector on their site. I couldn’t wait to get a PCB made up to facilitate the easy hacking/adding of hardware on to the ‘Pi. All the more important considering the ‘Pi’s aim of providing a cheap platform for people to learn all about hands on computing. The MoPI allows you to connect directly to the ‘PI and prototype designs using both through hole and surface mount components. Secondly it provides locations for stand offs or feet to allow the user to keep the board off the wire infested desk or mount it in a case. Thirdly it provides several ways of powering either just your project or also the ‘PI it’s self, we use a very common “Jelly Bean” regulator available cheaply from EBAY good for 2-3A. The regulator is adjustable allowing for many different uses, other than powering the ‘PI. Alternatively you can power your design using the DC Jack or 0.2″ Screw terminals. We have gone to great efforts to be as general as possible allowing people to do what they want.
This is a good example of what can be rapidly prototyped using home/keen amateur PCB manufacturing techniques like those we hope to demonstrate at our February meeting.
Hopefully this will be the start of much more Linux Hardware/Software hacking.
