DSO138 Mini Digital Oscilloscope DIY Kit Aembled ARM Cortex- 12-Bit TFT Oscilloscope 10:1 Probe Test Clip

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 makeMCU and LCD stay in one PCBto avoid problematic pin-header connections that was used in DSO138. This not only increase product reliability but also allow the main board tobecome a flexible general purpose controller.

DSO138mini'striggercan work reliably under 10us and 20us timebasesettings.Waveform data can be outputted through serial port and the data can be easily displayed on PCwith help of other like Gnuplot.Thisphotoshows the same waveform displayed on PC using Gnuplot.
