DSO138mini brings in the following improvements
1. Better structure and smaller size
2. USB or battery powered.
3. External trigger input.
4. The serial output of waveform data.
5. General controller.
DSO138mini make MCU and LCD stay in one PCB to avoid problematic pin-header connections that was used in DSO138. This not only increases product reliability but also allows the main board to become a flexible general-purpose controller.
DSO138mini’s trigger can work reliably under 10us and 20us timebase settings. Waveform data can be outputted through serial port and the data can be easily displayed on PC with help of other software like Gnuplot. This photo shows the same waveform displayed on PC using Gnuplot.

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.
