DSO138 Upgraded DIY Digital Oscilloscope Kit 13803K Version for Measuring Waveform

Description:
DSO138 was designed as a training oscilloscope kit. Simplicity in structure and easiness in assembly / operation are among the main targets of the design. For these purpose DSO138 uses mostly through hole parts. The heart of DSO138 is a Cortex - M3 ARM processor (STM32F103C8) from ST. It uses 2.4 inch TFT LCD (320 x 240 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematc. Source codes are also available to allow user to add their own features.

Main Features:
● Significantly lowered noises
● Waveform can be saved to recall from non - volatile memory
● Enhancement in test mode with auto short-circuit detection capability
● Supports two types of TFT controllers (ILI9341 and ILI9325 / 9328)
● Coupling modes: DC / AC / GND
● 1Hz / 3.3V square wave test signal source

Q

What is the max AC and DC voltage? I mean the voltage it is able to probe, not the voltage of the power supply. Are we able to probe 230V AC directly at mains power outlet or other other similar "high" voltages up to 1000 V like we can do with a regular Multimeter? Best Regards.

Hello Cidi,

The Simple probe of the item can be used to watch the signal within 50V.

If you use the BNC probe, then you can watch the signal  within 400V.

The oscillo probe can not be detected.

You can use it to watch the waveform.


Q

if i buy "Welding" i dont have to weld nothing?

Hello,

If you buy "Welding", the item a semi-finished products,it just welding some patch,you still need to welding some part by yourself.


Q

I received this item as a kit of parts and not a preassembled unit. How can I get the described preassembled unit.

Hello john,

Thanks for your inquiry. Partial products still need you to weld by yourself, even though you've chosen WELDING. Have a nice day.

Q

Why don't you send this item 'WELDING AS THE PICTURE' ? TWICE?

Hi andreas,

Thank you for your inquiry.Output Voltage: DC 9V.

Q

Hi, The description of the DSO138 Upgraded 13803K DIY Digital Oscilloscope Kit says "WELDING AS THE PICTURE", and the picture shows a fully assembled kit. The description also says "● The kit has been welded, so you can use it directly without assembling". Is this correct? The description sounds like the item is a ready to use oscilloscope.

    Product Overview
    Color:as the picture Size:WELDING
    I ordered the kit not knowing what to expect. I never heard of GearBest before so I was a bit skeptical of course. The price won me over and I went ahead and took the risk. I made my order that included this kit. I live in Oklahoma, USA so I expected a long delivery time. It took between 3-4 weeks. I finally received my O-Scope too and could not have been more excited. the kit arrived with the board, a screen, some instructions, and bag filled with components. In all honesty, I am not a great solderer, (is that a word?, anyways), I was excited to attempt this project with optimism. The instructions were written really well. In fact, I write manuals for my job and was really impressed with the documentation. The pictures were very helpful. Notes were nicely highlighted to warn of possible issues. Thought was put into the process. The steps have you solder the lowest profile components first, then the next tallest, and so forth. This allows for a fairly level height when the board is placed upon its back when soldering the leads. The steps were clearly defined, and the soldering went very well. I did check the Ω of each resistor before placing it onto the board due to the warnings from other reviews, but I found no issues. All of the components matched and all of the parts was present. After welding all of the components, I followed the instructions and applied power. As instructed, I tested the voltage at a certain test point. All was good. It then had me solder a junction point to complete the circuit. I applied powered again, and the unit powered up. I was amazed, jubilated actually. It works!!! It as an amazing little gadget with some great capabilities. Granted, it is not a several hundred dollars O-Scope. Nonetheless, it is great tool for the hobbyist. I have been using it for several days and it has been invaluable with my current Arduino project. Being able to see the signal in real time is such a necessity when working with electronics. I can now see my PWM square wave. Very Awesome!! If you made it this far and are considering purchasing this unit, my advice would be to follow the instructions completely. Read over them perhaps a couple of times before attempting just to fully comprehend the instructions in their entirety. If you are new to welding, soldering, then watch some youtube videos, practice a bit, and you will be fine. If I can do it, then anybody can. I am very happy with this purchase, Where else could you find a functional, however novice, O-Scope for less $20. JYETech did a great job putting this board together. Best of luck:)
    Suggestion
    Shipping takes a while. Expect anywhere from 3-5 weeks if you are in the USA. What can you expect: low priced goods from China with free shipping. Worth the wait.

    Self assembly oscilloscope
    Color:as the picture Size:WELDING
    It is a good working low budget oscilloscope. It also comes with a handy external clamping cable. The assembly is pretty tricky at some point so decent soldering experience is adviced. Also a multimeter comes in handy for checking on the resistors.
    Suggestion
    Assembly takes quite some time and the heat might damage a micro controller.

    Good DIY Kit
    Color:as the picture Size:WELDING
    -It works ! I had the kit up and running in just a few evenings of work. -The interface is pretty intuitive, despite its simplicity. -The manual outlines several test points before you add the LCD to make sure everything works. -The price makes this a very accessibly oscilloscope.
    Suggestion
    -Check every resistor with a multi meter to ensure they are the correct ones. I had couple that were mislabelled. -The instructions are laid out properly, but may be vague at spots. Just double check, and check again, make sure you have everything right before powering the unit up.

    Verry good
    Color:as the picture Size:NO WELDING
    I bought it just to learn soldering and didn't expect the oscilloscope will actually work. It is great fun to solder the kit, and the oscilloscope is very handy in testing electronic signals ( i used it to test rs232 from Raspberry PI RX and TX pins ).
    Suggestion
    Changing settings with buttons is hard, although i have old software version.

    The SMD parts were already soldered, which helped me a lot. The guides were usefull and overall it was easy to build.
    Suggestion
    The kit arrived only in a plastic bag. I would expect at least a box for it.
