Raspberry Pi beginner here. I've been looking at these beasts for a while. I'm very comfortable with programming and command line, but want to start playing around with electronics powered by software. By that I mean, physical hardware controlled by currents controlled by logic within the Pi.

I saw some interesting guides already that introduce in controlling DC motors with a pi, for example. If I fork out for the Pi 2, will that be suitable? I don't mind it being overkill if it is, I'm likely to try many different things with it. Controlling a motor's rotations is simply the start.

Thanks guys!

    I'd go for the Pi2. It will let you do everything you want - just slightly faster! - and for the same price!

    Whether the Pi 2 is actually the same price depends on who you order it from.

If you are using this for electronics you might as opt for a 40 pin model, i.e., A+/B+/2. The only advantage the B+ has over the 2 is very slightly lower power usage. If power usage is a big concern and you don't need ethernet, etc., you could go for the A+.

Most people are going to want the Pi 2 here, however. It is significantly faster, has twice as much RAM, and because of the more common architecture, can run a wider variety of operating systems.

  • Thanks @goldilocks and everyone else. Seems Pi2 is flexible enough to be the best fit. Let the experimenting begin!
