#NEW #DSO138mini #Digital #Oscilloscope #Kit #DIY #Learning #Pocket-size #DSO138 #Upgrade 100% brand new and high quality Features: DSO138mini brings in the following improvements: 1.Better structure and smaller size 2.USB or battery powered. 3.External trigger input. 4.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 increase product reliability but also allow 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.
