DSO Nano v2 - Pocket-size color digital oscilloscope - v2.0

This cute pocket oscilloscope is a perfect companion to your tool box. For beginners, its a good starter scope - it is not as complicated as a benchtop scope so its easy to use. For advanced EE's, its useful as a scope-on-the-go, for field-debugging, when you don't want to drag your scope over, or when a floating-ground is needed (it will naturally do 'differential' measurements as long as its not plugged into a computer USB port). It's not a terribly fast scope, best used for signals up to 100KHz, and it is only a single channel, but we still find uses for it all the time, especially with analog projects!
