Great news for inventors came from the creators of the single-board computer Raspberry Pi recently. Now on sale is a new version of it called the Raspberry Pi Model A+. It differs from Model A primarily in length of the PCB which has been reduced from 86 to 65 mm with Model A+; the only negative consequence of this was the reduction in the number of USB-ports from 4 to 1. Outside the one drawback, the Raspberry Pi Model A+ comes with a few upgrades as well. The GPIO header has been upsized to 40 pins, a new push-push micro SD slot replaces the old, frustrating, friction-fit slots, and better audio is also promised with a dedicated, low-noise power supply incorporated into the audio circuit. Its core computational capabilities are provided by a Broadcomm BCM2385 ARM11 processor with 700 MHz and 256 MB RAM. To date, Raspberry Pi Model A + on sale only in the US and the UK for about $20 before shipping.
