Raspberry Pi PCs hit with minor hardware delay

Last week, the $35 version of the Linux-based Raspberry Pi PCs finally went on sale after months of development. The first units immediately sold out, as one might have expected. However, the Raspberry Pi Foundation has now announced via its blog that it has discovered a hardware issue in the first batch of PCs.

According to the blog site, the specific problem was due to an accidental parts substitution at the PC's factory:

 ... specifically, where we’d specified jacks with integrated magnetics in the BOM and schematics, the factory soldered in non-magnetic jacks. No magnetics means no network connection. We’ve known about this for four days now, but we haven’t been able to tell you about it because it meant we had to do some further tests to make sure that nothing else was affected.

This has caused a delay in the first shipment of the Raspberry Pi PCs as the factory works to replace the jacks with the correct magnetic version. The blog site states that the factory is almost done with this procedure and as a result the people who ordered the first units will still receive them. However, later production runs could be delayed slightly as the company tries to find more magnetic jacks.

Mines on order, but in the two months between me placing it and it arriving I hope I won't have changed my mind about getting one

You can always sell it to me on ebay.

At that price, it should be anything that breaks the bank.

why does having a non magnetic jack mean no network connection? It should still work, just with more EMI radiating from the ethernet cable.

Internal magnetics is more than just magnetics:

"These integrated magnetics, resistors and/or capacitors filter common-mode noise to provide signal integrity, protect PHY chips, provide DC isolation and offer low-mode conversion"

I've tried to make a board work with the wrong resistors on the lines, and it didn't work at all. Let alone with no resistors.

The worst thing is if you didn't get in the first batch you are going to have to wait till late May early June for the next batch.

I really want one of these.

I think it's great that they're so open about the issue.

They're being completely open about (AFAIK) everything, which seems to be really working in their favour. Because they talk about their problems, it gives the impression that they respect the community, which then gets reciprocated.

Bigger companies should be taking notes.

People seem to be forgetting that they're not making these embedded computers for the whole world to make an HTPC, they're making as-cheap-as-possible computers to stimulate the learning (and having fun) to program stuff.

I think they should've added some sort of a small markup (involuntairy donation, if you will) on sales of raspberry-pi boards to private individuals.

That way they can at least get some nice funding on the next boards and other RnD work.

Even so, I reckon that if the big companies provided this kind of feedback to their customers, it'd forge a trust with the community that'd turn into a good reputation.

Fortunately this was discovered before they shipped them, would of been a heck of a lot more expensive if everyone had received their devices.
