I have just read that there is a new model Raspberry Pi coming called the A+. What are the improvements added to this board and how does it compare with the recently released Model B+?

Are there any software restrictions that apply to the A+ that do not apply to the B+ (or even the B)?

There are several improvements most of which mirror those introduced with the model B+:

  • A smaller form factor compared to the other models (including the A),
  • Improved layout (compared to the model A),
  • Combined 4-pole jack for connecting your stereo audio out and composite video out (like the model B),
  • Better audio. The audio circuit incorporates a dedicated low-noise power supply (compared to the Model A and B).
  • Expanded GPIO, now comes with 40 GPIO pins like the B+ (the A and B models only had 26) and is compatible with the HAT standard for add-on boards. See Joan's comment below regarding the usable number of GPIO pins.
  • Better power management (compared to the A + B models).
  • Now uses a micro SD card (compared to the model A).
  • It is also cheaper $20.

As for software you may need to be running a newer version of the Kernel and Firmware, like with the B+.
