DSO 138 Mini Oscilloscope DIY Handheld Portable USB Digital Storage DIY parts with shell

• --Better structure and smaller size
• --USB or battery powered.
• --External trigger input.
• --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..
• --DSO138mini make MCU and LCD stay in one PCB to avoid problematic pin-header connections that was used in DSO138, increase product reliability,become a flexible general purpose controller.

--DSO138mini make MCU and LCD stay in one PCB to avoid problematic pin-header connections that was used in DSO138. This not only increase product reliability but also allow the main board to become a flexible general purpose controller.
