Description
DSO138mini brings in the following improvements:
Better structure and smaller size. The bulky pin-headers connecting the LCD and main board in old DSO138 has been eliminated. The soldering of these pin-headers has being found problematic for beginners.
USB or battery powered. This makes the scope much more convenient to be used as a portable device. New version analog board (PN: 109-13801-00H, aka "H version") can accommodate a battery charger JYE118 (see here) to make the device more practical.
External trigger input. This input can accept a TTL or LVTTL signal as trigger source.
Serial output of waveform data. This means captured data can be saved and displayed by PC. For example, this photo shows a captured single byte (0x35) sent from a serial port at 115200bps. This photo shows the same waveform displayed on PC using Gnuplot.
General controller. The main board can be used as a general purpose control board with LCD display. MCU ports were brought to board edges for easy connection to the target system.
There are a few optional parts that can be chosen to make the oscilloscope even more complete:
BNC connector. The kit comes with a two-pin header for the simple hook probes (see the manual). This connector replaces the two-pin header and will allow you to connect to standard professional BNC probe.
Standard BNC probe.

I use it to measure my electronics projects, it's a great and especially portable tool
P****y
This tiny O-scope is handy if you have a portable bench. To get the most out of it, I recommend adding some velcro to keep it in the larger travel case. It's so small that it slides around when you move the probe.
Q****n
If you're looking for hobbyist stuff, this is a great product. Obviously not suitable for professional labs, but works well if you are building kits and diagnosing personal electronics.
E****n
This will by no means replace your bench oscilloscope, but does a great job under your dashboard or under the hood of your car.
