JYE Tech DSO138 Mini Digital Oscilloscope DIY Kit SMD Parts Pre-soldered Electronic Learning Set 1MSa/s 0-200KHz

Features:
2.4-inch color TFT LCD with 320*240 resolution displays parameters clearly.
Make MCU and LCD stay in one PCB to avoid problematic pin-header connections.
Overall size of DSO138mini is only 2/3 of DSO138 so it is much more suitable for hand-held operation.
Improvements in power supply and mechanical structure, it can run on USB or a single cell 3.7V Li-ion battery.
Can be connected with computer for data transmission.
DSO138mini has improvements in firmware, too.
Its trigger can work reliably under 10us and 20us timebase settings.
With Auto/Normal/Single trigger modes, easy to capture the moment waveform.
Available rising or falling edge trigger.
Observable previous trigger waveform (negative delay).
Can freeze at any time waveform display (HOLD function).
Waveform storage function: will not lose the waveform after power off.
Short-circuit and open-circuit detection: can help the user find out the soldering error.
TFT controller recognition function.
All SMD parts has been soldered and the MCU has been programmed.
Note:
The SMD parts in this DIY kit has been soldered, you just need to solder other parts by yourself.
