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 Adafruit still find uses for it all the time, especially with analog projects! The new version 3.0 has a nice fully-metal case for increased durability

DSO Nano manual

Please note! The case is metal, so do not use the DSO on high voltages above earth ground! Also, while plugged into a USB port, the ground probe and case will be connected to Earth ground through the PC so do not connect the ground probe to a voltage above Earth ground.
