The Raspberry Pi Foundation has released a new lower-power, smaller, and amazingly cheaper Raspberry Pi version called the Raspberry Pi Model A+. The model retails for $20.
A slightly more detailed analysis of the board can be found at Raspi Today with information on exact weight, dimensions, and power consumption.
Raspberry Pi Model A+ out now. 20% cheaper, 24% shorter and 42% thinner! You can buy a Raspberry Pi Model A+ right now. It costs around $20/£15, it's just 56mm long, 12mm thick and uses up to 45% less power than a Model B+"¦ Model A+ Specs: Dimensions: 65x56x12mm Memory: 256MB RAM Expansion: Micro SD slot, 1x USB, 40x GPIO Networking: None Price: ~$20/£15 Weight:
The freshly updated version of the Model A does much more than simply bring it in line with the Raspberry Pi Model B+ released in the summer. The Raspberry Pi Model A+ is the same dimensions as a HAT (Hardware Attached on Top) add-on board, the same price as two cinema tickets and can run at nearly half the power consumption as the Model B+.
Since it uses the same improved power chain as the Model B+, the Model A+ consumes much less power than any other Raspberry Pi. According to its designer, James Adams, running the same 'hello_teapot' demo with a USB keyboard and a HDMI monitor connected the Model B+ consumes 370mA, while the A+ consumes just 200mA - 45% less power under the same conditions.
