The Raspberry Pi Model A (the cheaper, stripped-down version) was just released for $25.
How is this news? Well, I thought the Model A was already available.
It has half the memory of a Model B, and no Ethernet, and only a single USB port.
If you’d like to be able to mess around with microcontrollers but prefer a self-contained environment, a Model A has potential, and the price isn’t all that high. I’d still probably develop on the $35 Model B so I can connect to it remotely, then swap the SD card into the Model A and put the Model A into use. But in a pinch, just plug the Model B in to a USB keyboard and the nearest LCD TV.
