This DIY digital oscilloscope kit adopts ARM Cortex-M3 processor and with 2.4-inch TFT screen and protective case. It's easy and reliable for circuit operation. It can display waveform parameters, such as frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.

Features:
Can freeze waveform display at any time(HOLD function).
With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.
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.
The SMD has been soldered, more suitable for electronic beginner.

Notice:
When you receive this DIY kit, please don't solder it before connecting with DC 9V power to test the circuit board, the board is normal if it displays scanning line; if the display is abnormal, please contact us.
