This DSO311 DIY digital mini oscilloscope kit adopts STM32 chip, 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. This mini oscilloscope is designed for electronic hobbyists to learn about electronics, soldering, programming and STM32.

Features:
Can freeze waveform display at any time(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.
The SMD has been soldered, more suitable for electronic beginner.Great DIY kit and fun to make your own oscilloscope.

Notice: When you receive this DIY kit, please don't solder it before connecting with DC 9V 200mA power supply to test the circuit board(no more than 10V, or it may be burned).
