Everyone's favorite minicomputer has just gotten even smaller. The Raspberry Pi Foundation is today introducing the Model A+, a revamped version of its low-end Model A board priced at just $20 (20 in the UK). While the processor and RAM -- a Broadcom BCM2835 SoC and 256MB, to be specific -- remain the same as its predecessor, the new model is far smaller at just 65mm (2.6 inches) in length versus the old model's 86mm (3.4 inches). It also draws less power and has improved audio circuitry.
