Rummaging through my "junk box" of designs I came across an SD memory card module I did a couple of years ago. It's basically a Prop and SD card that can operate stand-alone or plugged into another board either directly or through an IDC cable. 16 general-purpose I/O are available with optional pull-up/down resnets, plus the boot lines and the board includes an LDO regualtor so you can run it from 3.3V to 9V or so (spec'd for 5V). There are also 2 indicator front panel leds plus pins for TV. Board size is around 1.5" x 1.4".

I'm fixing up the spec sheet for this and I have plenty of stock as there is the customer who needs these modules as an ongoing item. Software uses a modified fsrw for the SD card.

I don't normally sell boards directly but they seem like a handy module so as an offer regular forum members can purchase them for $49 USD.

Agreed - looks very nice. I'm interested in a small 1.5" x2" USB-powered type of Propeller module with key I/O dedicated to TV, audio, one PS2, and remaining I/O, 3.3 + 5 VDC connections available via header pins. I'm interested in something quite small that I can program on airplanes or use in other space-constrained applications. I haven't fully defined my Prop "dream board" yet but I hope to do that in 2009 when I lay out my first PCB. Yes, you read that correctly.

If you (or anybody else) want your Propeller creations shown on our Customer Applications or 3rd Party Tools web pages please let me know. We can post whatever information you provide and make links to your on-line ordering locations.

Awesome cards!


The quest for the perfect Propeller board... Good Luck, I've been trying for 3 years. :)
{Guess I'm going to have to learn PCB design too.. }

Ken, thanks, this board wasn't really designed to be small because I could have used microSD instead and thin pcb laminate etc but the standard SD is meant to be removed/inserted frequently. This one may be close to what to need though. As for PCB design well I started with tape and film where you couldn't just cut & paste or autoroute or anything. So any way at all at being able to do it on a computer is infinitely easier. However there are so many freebie pcb solutions that you have to stop and think if you are getting into it. I like Protel99SE myself but I am looking around at ones that run directly on Linux or through Wine and that DipTrace one looks good and is low cost plus there are no penalties for upgrading later. Still checking them out though.

I have never used Eagle other than for evaluation and I think it's like some of these old European towns that are a hodge-podge of streets and lanes which aren't a problem if you grew up there.

I do have a lot of board level products that I could sell so I might setup a PayPal account more as a bit of a service and out of interest. I know some people think certain products are cheap while to others they are expensive but you get what you pay for sometimes. Sometimes there is way more profit in simple "adaptor" boards then there is in a complete solution.

Protel99SE was Parallax's standard program for all PCB layout up until about two years ago. The guys who used it kept nursing it along and knew the various nuances of making it do what they wanted it to do. They had a particularly good understanding of how to get the most out of it without causing a crash and they refused to pander to the Protel upgrade salesmen. The IT Guy really hated it as he didn't have control over the installation process and the PCB guys held onto the installation CDs. But it was used successfully for many board designs at Parallax. It wasn't until Thomas came to work that we switched to PADS.

I'll probably use Eagle since we purchased a half-dozen licenses a while ago. Only Chris is using one of them as far as I know.

@Ken, Times have changed at Protel (Now Altium) as they are practically giving away the Altium Designer now.
