It also uses 45 per cent less power than a Model B+. It's on sale now for $20/£15.



From Hexus:

The Raspberry Pi Model A+ is the first RasPi to shrink below the 'credit card sized' standard that was set with the first model. The smaller size (around 55 x 65mm) will allow the computer to fit into even more portable and discrete situations. Its power consumption reduction will aid in portability as any battery drain will be reduced proportionately to the 45 per cent drop in consumption.

Compared to the B+ you lose the Ethernet network socket, have only 1 USB port and only half the RAM, (256MB rather than 512MB). But you still have many of the B+ 'essentials' including the 700MHz BCM2835 application processor, HAT standard GPIO header with 40 pins, push-push microSD and improved audio. Mount holes are kept in the same place of the circuit board for compatibility.

  Raspberry Pi Model A+ is smaller, thinner, cheaper
