Raspberry Pi Model A Breaks Cover, Lower Cost, Lower Power
Just because the Raspberry Pi Model A is newer doesn’t mean that it’s better, though. Raspberry designed the two Pis for different uses. Where the Model B is aimed at DIYers and educational settings, the Model A is expected to be used widely in industrial settings. Consequently, Raspberry focused on lower power requirements. The Model A has 256MB of RAM (to the Model B’s 512MB) and the Model A lacks an Ethernet port.
“We’re seeing demand for the Model A from people making industrial control modules, from roboticists, from people doing automation, for a bunch of headless operations – and, significantly, for people who want to use the Pi as a very cheap media centre. The Model A will only cost $25 (plus tax and shipping),” Raspberry says on its website.
