LONDON – The Model A version of the credit-card sized Raspberry Pi computer is becoming available in Europe for a price of about $25.
The Model A is a stripped-down version of the Model B Raspberry Pi, which has been on sale for some time, but with no Ethernet, a single USB port and 256-Mbytes of RAM.
Stripping down the Model A means it is $10 lower cost than the Model B but perhaps more interestingly for some users is that it consumes about one-third of the power of the Model B. So for battery- or solar-powered applications, such as robots, sensor platforms in remote locations, industrial automation, datalogging and so on the Model A is a better option. There is discussion of rewriting software to reduce power consumpion yet further to perhaps a tenth of the current level on the Model B board.
Customers outside Europe can order a Model A Raspberry Pi, but there will be a short delay in processing their order waiting on some paperwork, according to the Raspberry Pi website.
