First Picture of Craignell Modules

No Link ? ( some of us are lazy..)

Thanks, but on the home page Craignell Modules does not appear, and google for Craignell Modules finds nothing, also news has only quite old infos, and not until I take a guess, and dig into BoardProducts do I see Craignell mentioned, and finally here find a link

Tip for John: Post photos in two resolutions: Lower for fast loading, and then click-on any photo, to allow higher res.

There seem to be 3 variants, but all labeled FD2 ?, and these all seem to have two 'Pin1 Square pad convention' - also no photo of the PCB rear ? I can see a compact flash card, but no mention of how that relates to Craignell Modules - is there a CF socket on the rear ?

Not set in stone yet but one off prices are likely to be GBP=A325-30, US$ 40-50 on current exchange, for the base level versions with the XC3S100E. If it starts to ship in reasonable numbers it is likely we will drop that price back a bit. Certainly discounts will be there for orders of 10+ even at the initial production run rate.

The 3 versions we have done are 32,36 and 40 pins. We will probably do a 28pin and maybe 48pins as well. Anything up to 42 pins is easy as we don't change the core design. We just hook up more signals to the bus switches than provide the 5V protection. Beyond that we add another bus switch but there is area available in the bigger pinouts.

CFCARD merely there to show size for those wondering.

We are aiming for these to be a stock item towards the end of Feb but that is subject to usual spanners in the works.

I'm no longer in an academic role, but it seems to me that you have there something that will be very, very desirable as a component of many undergraduate projects.

Some silly questions: (1) is there room on the (back of???) the board for a config ROM? (2) is there room on the back for a modest-sized SDRAM?

Obviously, neither need be populated on low-cost versions.

Nice product.

What the current photo does not show is the serial flash that resides on the back of each of these modules for configuration but also as a code storage device. At the moment this module does not have a sram and certainly on the smallest of these module probably is not possible.

We do hope that these modules do have uptake in university projects and a few other sectors as well. Time will tell but generally I think these will fufill some needs out there.

For modules with SRAM we have the Darnaw1 which is running through at the moment. Photos in a couple weeks I hope. It is a very similar concept except no 5V tolerance and a lot more pins. As with anything we do it is possible to do derivative designs if there is commercial sense for us to do so. Just needs someone to make a good case to us to do it.

How is the solder pads parallell to the dip holes wired?, I assumed first directly to dip terminals, but then the pcb photo seems to suggest otherwise.

Can the 5V tolerant I/O directions be set per pin or is it required to be set in chunks of 4,8,16 bits etc.. ?

Btw, any chance for a metric ruler in the photo? ;)

Thanks for a good product anyway.

Any limit in frequency, ampere-load, capacitance?
