DSO328 2.4 Inch TFT LCD Atmega328p Mini Digital Handheld Oscilloscope SMT32 12 Bit Probe BNC Beyond DSO138 DSO311 DC 9V DIY Kit


Sale price $36.99 Regular price $55.48

Tax included.


This mini oscilloscope is designed for electronic hobbyists to learn about electronics, soldering, programming and STM32. It contains main controller board, TFT LCD and other electronic components to DIY a functional mini digital oscilloscope.
Use STM32 Chip. It runs faster than DSO138 and a good handle of data.
Pre-programmed. The controller board is programmed and tested before leaving factory. It is high quality and safe to use.
Full of Fun. It is a DIY kit and fun to make your own oscilloscope. Especially suitable for who are interested in soldering and STM32.
With Cool Black Case. Unlike DSO138, this DS0311 is with a cook black case, which makes it convenient to use in teaching and testing.

Display and Control
Power Supply: DC 8V-10V, recommend DC 9V, no more than 10V
Probe: connect the probe to BNC
Button Functions:
【V/DIV】: Selection for Sensitivity and Vertical position
【SEC/DIV】: Selection for time base and horizontal position,
【TRIGGER】: Selection for Trigger mode, Trigger Level or Trigger Edge
【OK】: Press once to entert HOLD function, second press to exit HOLD function
【ADJ】: Arrow key, turn left and right to select parameters Selected parameter will be highlighted
【COUPLING SWITHC】: Coupling can be switched to DC, AC or GND. When it is switched to GND, the oscilloscope's input is disconnected from external input and is connected to the ground, aka input is 0 V
Function Operation
Vertical position alignment Switch to GND, press【V/DIV】for 3 seconds
Parameter bar turn on/off Press【OK】for 3 seconds to turn on/off the parameter bar.
Save waveform Press 【OK】and 【TRIGGER 】at the same time, current
waveform will be saved in EEPROM; the original data will be replaced.
Read waveform Press【OK】and【SEC/DIV】at the same time,it can read the
waveform saved in EEPROM;it is showed in HOLD mode.
Reset to default setting Press【SEC/DIV】and【TRIGGER】for 3 seconds
Horizontal position centered Press【SEC/DIV】for 3 seconds, horizontal position will be in
the center of waveform buffer
Trigger level centered Press【TRIGGER】for 3 seconds, Trigger level will be in the
center of Signal amplitude.
Probe-compensated adjustment:
Adjust trimmer capacitor C3 and C5:
Connect the probe's RED clip to signal output terminal, black clip not connecte
Power on the oscilloscope to start, press【ADJ】knob for 3 seconds. Tthe bottom of the screen shows the output of the test signal amplitude, and then press【ADJ】 to adjust amplitude to 0.1V
Set sensitivity to 50mV, adjust trigger level to make the waveform stable
Adjust C3 to make the waveform right-angled. C3 adjustment is finished
Press【ADJ】to adjust amplitude to 3.3V, and set sensitivity to 1V, adjust C5 to make the waveform right-angled.
