Unfortunately we have been notified of a component supply problem with the specific push-pull type SD card holder used in the design (Dec. 11 EPE)

After going to press we have today learned that Jaycar can no longer obtain that particular SD card socket. The Chinese manufacturer will only supply orders of 10,000+ which is not feasible for the hobbyist market. Jaycar has been unable to source an alternative card with the same pinouts.

With Silicon Chip's help we located what seems to be a replacement (non-UK) but stocks of that are also said to be low. Other types that I've looked at have different pin numbers and all are on lead times of several weeks.

Until PCBs' can be revised, we are trying to design a workaround. This may involve a small board that carries a regular SD card socket, hooked up with jumper wires or other adapter, or some other idea.

Future projects will need a different SD card holder and any legacy EPE/ SC projects will need an adapter interface board if a direct replacement can't be found.

Obviously this isn't the news we wanted to bring our readers. This kind of problem is very rare but parts can go obsolete without warning or remaining stocks can be snapped up by eg a manufacturer for production purposes, making life very difficult for the hobbyist.

The best we can say at this stage is that we are looking at this very closely to see what we can offer and we will be updating readers here or by Email.

Thanks for understanding that this was unforeseable and unavoidable, and we'll do everything we can to provide a workaround as soon as possible.

An update was published in the Feb 2012 issue which describes a small daughterboard modification, and there is also plenty of help on this topic from readers elsewhere in the Chat Zone forum.
