Manufacturing problems will mean the
first batches of the £22 ($35) Raspberry Pi computer, aimed at helping people
learn programming, are delayed.
The error has caused a "hiccup" in the production of the eagerly-anticipated
credit-card sized computer.
The mistake meant that the wrong type of networking jack was soldered into
place on some of the circuit boards.
This might also have a knock-on effect and delay future production runs of
Released in late February, the Raspberry Pi has been developed to be a cheap
computer that will help children and other beginners get to grips with computer
The machine is available in two models. A model "A" without networking and a
model "B" that comes with a network jack.
However, Raspberry Pi
announced on its blog that some of the parts making up the first batch of
the model Bs had been accidentally switched in the Chinese factory where they
are being made. Production has been outsourced to China in a bid to keep costs
of the bare-bones machine in check.
The component in question is a specific type of ethernet jack or
Unfortunately, the factory soldered on the wrong type of jack which, if left
in place, would leave the gadget unable to connect to a computer
Swapping the wrong jacks for the right ones on the boards that were already
made up was a "minor problem to fix", said Raspberry Pi. However, it added,
there might be a delay for future gadgets as it sought sources of the correct
Large stocks of the wrong component had been built up as production got
going, it said, and these were now being swapped for the right ethernet
"We are very, very sorry," wrote Raspberry Pi community manager Liz Upton on
the organisation's blog.
The bare-bones computer project has proved hugely popular and the websites of
two of the firms contracted to build the machines crashed when the Pi went on
general sale. All three firms that signed up to distribute the machine have sold
their initial stock.
Anyone wanting to buy one can now only register their interest rather than
place an order and wait until more stock is received.
