The Raspberry Pi microcomputer, the favorite gadget of inventors, makers and tinkerers around the world, has been getting some face lifts lately.
Back in July, The Raspberry Pi Foundation announced the Model B+, an upgrade from the popular Model B that had lots of new features, but not any more power for the microcomputer. The foundation has now set its sights on the smaller model in the Raspberry Pi family, releasing the Model A+ on Monday.
The Model A+ is the next version of the lower-cost, lower-power consuming Model A. This upgrade pushes the model to an even lower cost and even less power consumption. Where the Model A cost $25, the A+ costs only $20.Some of the new features are the same that the foundation gave to the Model B+:
-More GPIO. The GPIO header has grown to 40 pins. The Model A+ is compatible with the HAT standard for add-on boards.
-Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
-Better audio. The audio circuit incorporates a dedicated low-noise power supply.
It is also smaller than the previous model (65mm in length, versus 86mm for the Model A), but packs the same BCM2835 application processor and 256MB of RAM.
Judging by the comments around the web, tinkerers and makers are excited to get their hands on this model and make a lot of robots. We're excited to see the results.
