More Arduino Project Stuff

Just thought I would make a quick entry in a couple of spare minutes to state that I have decided to “split” the Arduino system, well rather the PCB’s as I was simply trying to do to much on one PCB so what I have done is split the power supply onto one board, and as I am splitting it I have taken the opportunity to add a second regulator to the design for 3.3volt along with its associated smoothing capacitors so I can integrate 3.3v electronics into the system in the future if I want, besides I can then intergrate the powerboard design into other projects making the extra PCB’s I will purchase usefull as most places have a minimum run of 4 or 5, which means that for the once of projects its not paticuarly useful, but if I design it right the first time I can use the board on other projects as well. On this board as well will be the two OPAMP’s and the linear optocoupler to allow for the monitoring of the power via a plug in lead to the board, meaning that in total there will be 2 leads to the board, the first one carrying power (12VDC, 5VDC, 3.3VDC and ground) and the second one being the voltage monitoring.

I will release the designs for it once I have built it and tested it
