This morning the Raspberry Pi Foundation released its update to the Model A revision of the Raspberry Pi. The new Raspberry Pi Model A+ features the same BCM2835 processor, and 256MB of RAM that the previous Model A utilized, but the Model A+ differs in size, power consumption, and clutter. The Model A+ features a 40-pin GPIO connectort now which breaks out additional GPIO pins as well as conforms to the new HAT standard for better module board compatibility. Additionally the switch was made from a standard sized SD card slot to the more compact and flush mounting microSD card slot making the new smaller board even smaller. The A+ also features a more sensable mounting hole placement, as well as updating the analog audio and video into a single 3.5mm jack.

The new Raspberry Pi Model A+ measures in at just 65mm x 56mm x 12mm, and features the majority of its connectors on just two sides of the board. Furthermore, the Model A+ has been reduced in price from $25 to just $20 at MCM Electronics thanks to its lower component count. The Raspberry Pi Model A+ features the same  improved power circuitry as the Model B+, but with less components, the Model A+ consumes much less power than any of the other Raspberry Pi models. According to its designer. Some reports show that the new Model A+ uses 45% less power than the B+ when tested under the same conditions. . It is important to note that unlike the Raspberry Pi Model B+, the Model A+ only features a single USB 2.0 port, and no ethernet connectivity. So if you plan on using this you will need to buy a good powered USB hub if you wish to use a wireless network dongle as well as a mouse and keyboard.
