The prototypes I received had a few issues – I neglected to add filtering caps for the supply as the original design didn’t need it – the Arduino host board had them. I also had a couple of wiring errors. The bigger issue was the lack of availability of another part – the three RCA connectors. It turns out that SparkFun no longer has these parts, and when I checked with their supplier (4UCON) the minimum order was 3000 pieces. Not happening.<\/p>\n\n\n\n

Version 2.0.2 has some corrections, and incorporates a triple RCA connector<\/a> that is available from Mouser. The jacks are spread out a little further as well, which is probably a good thing as the original was pretty tight due to the limitations of the Arduino Shield size. The 2.0.2 version is a little wider as well as longer.<\/p>\n\n\n\n

The board is now 3.5″ X 2.5″.<\/p>\n\n\n\n

I’ll order another set of prototypes to test, and hopefully be able to make a larger order to make available. The existing shield based version still works just fine, you just need to source a Arduino Duemilanove (or equivalent), and solder coax jumpers to panel mount RCA’s as the PCB mount RCA’s the board is designed for are unavailable.<\/p>\n\n\n\n
