The ultra-portable Raspberry Pi computer sold out in the US within hours of making its American debut.
Retailer Allied Electronics said that both the Model A and Model B versions of the Linux microcomputer were out of stock and that back orders may not be available to ship for as long as six weeks.
The release, and subsequent shortage, suggest that demand for the ultra-portable systems, which measure just 85.6mm by 53.98mm, is even higher in the US than the company had estimated.
According to reports, retail partners had stocked dozens of units in anticipation of the release.
The Raspberry Pi, which was developed in Cambridge, has grown into an icon of the UK technology sector. The systems are built entirely in the UK and the company has advocated investment in the nation's technology industry.
The US debut comes more than a year after the first Raspberry Pi models went on sale in the UK. The Linux systems are available in two models. The £19 model A system sports 256MB of RAM and a USB port on top of an ARM CPU. The £22 Model B sports 512MB of RAM and two USB ports as well as an Ethernet port.
Designed for hobbyist users and the education sector, the Raspberry Pi has proven a hit due to its small size and customisable nature.
