DSO138 was designed as a training oscilloscope kit. It performs the basic oscilloscope functions and is easy to use.
The heart of the DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses a 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element and provides clear waveforms.
DSO138 is partially open-sourced. This allows users to add different features or develop new applications on the hardware.
Although this kit comes with instructions on how to build it you will need some experience reading electrical diagrams.
NOTE: This kit has the SMT sodering done already

Note:This is a kit which requires users to have adequate soldering skills in order to complete. A Power supply is not included in the kit a 9V DC power supply is required to run DSO138. It is recommended to use the 5V-to-9V Step-up Converter JYE140 to power DSO138 by battery or USB.
Brilliant little kit. really useful for looking at PWM waveforms out of radio receivers and BEC power supplies for noise(ripple).
Is not a clone - it is original JYE product.
Surprisingly powerful features and very good documentation.
Suggest you use a multi-meter (to measure resistor values) and if possible use an LC meter to measure inductor (L) and capacitor (C) values before soldering onto the board
Received in 14 days from ordering to Australia. All parts were accounted for. I measured the values of the resistors to be certain they were correct. With sorting everything out to finished was around 3 hours . Did the calibration and all worked well. Found it to be a great tool for my learning curve with soldering and electronics in general. There is a lot of information on the net that is worth looking at to get a better understanding of its uses. Would definitely recommend.A desaster!
All voltages (including A-) were ok! Then after 2 minutes L2 and Q were burning. Q2 and U4 were also destroyed. So I replaced L2, Q1,Q2 , U4 and D1 and immediately the DSO138 was working. The reason for the failure was that the original L2 inductor was supplied as 1mH/0.3A instead of 1mH/1A !!! But one cant see that when looking at the component....
So there is really no quality control of the parts!
JuergenHey a great learner! the kids actually were interested and are thrilled to see it works!
Thanks! :)Finest quality, easy to solder, all you need is included.
The usb socket is not easy to solder, cause, the soldering points are very close, so it takes a steady hand.
Amazing product for the price
