DSO138Mini Digital Oscilloscope Kit DIY Learning Pocket-Size DSO138 Upgrade(Spare Parts) Popis

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. universal 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 universal 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 PC with help of other software like Gnuplot. This photo shows the same waveform displayed PC using Gnuplot.
