Description: This kit includes everything you need to build your very own, fully functional, digital oscilloscope. Once you’ve got it up and running, the oscilloscope features up to 5M samples/second, 8-bit resolution, up to 50Vpp max input voltage, and more!

This kit includes a semi-populated PCB, with all of the surface mount components already soldered on for you. The components left for you to solder are all through-hole. This is on the higher end of difficulty as far as through-hole kits go.

This kit pairs nicely with our BNC Probe Kit! A 9V power supply is required to run the oscilloscope; supply is not included.


  • 9VDC power supply voltage
  • <280mA current draw
  • 5M samples/second (AUTO mode only)
  • 8 bit resolution
  • 256 sample memory depth
  • 1MHz analog bandwidth
  • 100mV/Div-5V/Div sensitivity
  • 1MΩ impedance
  • 50Vpeak-to-peak max input voltage
  • DC/AC coupling
  • Save and display up to 6 captures to memory
  • Transfer screen capture to PC as a bitmap file (serial adapter not included)
  • Backlit LCD display
  • BNC Connector


  • 110x65x25mm
  • Weight: 70g

Customer Comments

  • Did I just buy this kit for 80 dollars here that I could have bought for 30 dollars less via the firmware link above (or 20 dollars less fully assembled)?

    It sure looks like it, and if so, I feel a bit silly for buying it here. :-(

    • Thank you for pointing this out to us! Our Customer Service team will be in contact with you soon to help resolve this issue.

  • This is a great kit and was easy to solder. A couple of things though. Note that included pins that need to be soldered for LCD are not standard 2.54mm pins but smaller ones, probably with pitch similar to XBee’s headers, so if they break or something, replacing them won’t be easy; soldering these pins is not easy as the pads are pretty small and somewhat oxidated, I had to put additional soldering flux on them to prevent cold joints and allow solder to bind to pads. When used with 12V supply, power regulator and its heatsink (I actually added a bit of thermal paste between them) get uncomfortably hot, but that can probably be modded to a 5V switching supply or a booster from LiPo battery. Also LCD initially required contrast adjustment as it was a bit washed out.

  • What a great bit of kit. I did a couple of mods, added an on off switch and a 9v battery lead . The on off switch I put in by lifting the +ve leg of the diode nearest the power connector and putting a switch in between the lifted leg and the hole it came out of, sleeving the lifted leg to switch end.. The 9v battery lead I soldered directly to the power connector contacts,. Now to mount it all in a neat little box. Why didn’t I get the probe kit!

  • The 50V Peak to Peak maximum voltage looks as if it occurs with a X1 probe. Would a X10 probe allow 500 v PP?

  • I really like this kit, and the specs look really good for general use…. I ordered one for my lab assistant.

    Looking over the design specs, it looks like it’s made for easy modification. I’d probably replace the push buttons with some knobs. I got one of those Nano V3 scopes from Sparkfun to play with, and I never use it because it’s too slow and clumsy to navigate through all the menus.

    P.S. About dual channel: The schematics show that most of the guts of the thing are taken up with the single channel circuitry (see the link above). Maybe a cheap way to add a second channel would be to order two of the kits and modify the software to multiplex them onto a single I2C bus LCD somehow.

  • Looks fantastic and a great price. Any chance of a dual channel ? That would be completely AWSOME even at double the price!

A fun project

The kit arrived well packed. It took roughly an hour to solder in parts. The documentation is good and easy to find. I have owned many Textronic scopes over the last 55 years but donated my last one to the ham club here. Then I needed a scope. For my use it is great, takes up very little room and is easy to use. Whether it is a first time scope or if you have used one for years, this is a good portable, fun tool. Bruce KT4ET

Good purchase

Was a fun kit to assemble and performs as advertised and expected. Would’ve been nice to have a power supply included but no problem. Overall I’m satisfied.

Buy from jyetech.com

I think the product is fine. Works well, easy to use. However I paid $79.95 for it from Sparkfun and on the documentation sheet it came with was an address for support at jyetech.com. When I went to that website I found the same oscilloscope on sale for $49.00. Needless to say I will not be buying from Sparkfun again without doing much more research. I feel ripped off! Update: After seeing the above review, I received an email from Sparkfun giving me a $20 credit matching the price I originally paid with the current price. I consider that very good customer service and am changing to 4 stars. Would be 5 except there is no case which would be nice. And it’s still $10 cheaper at Jyetech.

Hey there! I’m sorry about the inconvenience - please keep an eye out for an email from me addressing this. :)

Well Worth The Price And Effort

The instructions are excellent and the testing along the build process is great too. Some of the soldering is trickier, requiring some patience and a good soldering iron, but most of it is not too bad. Expect to be carefully adjusting the contrast of the screen at the end: it is only visible in a small range of the adjustment screw, so be patient there as well. In the end you’ll have a useful little tool. Much thanks to the Customer Service people at SparkFun as well, because I have yet to have an interaction with them that doesn’t make me a happier person.
