DSO320 1-Channel Mini Oscilloscope DIY kit

brand: SainSmart 1 SKU: 101-10-186

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 andSTM32.
  • With Cool Black Case. Unlike DSO138, SainSmart DSO320 is with a cool black case, which makes it convenient to use in teaching and testing.


Notice: This oscilloscope requires DC 9V 200mA power supply (no more than 10V, or it may be burned)

Great price, not for beginners

They take the DIY a little too far in this kit, all you get is a bunch of parts. Go online and all you get is minimal operating instructions and a parts list. Good luck putting it together, since there are not any assembly instructions, or even helpful photos. Luckily I seem to have gotten everything in the right place first time because it works great! I haven't checked the calibration for accuracy, and probably never will, because I basically just wanted it for some low frequency waveform watching which is what this thing does. And for $33, you can't beat it.
