The JYE Tech DSO150 is a one-channel, low-frequency oscilloscope kit best suited to learning basic waveform measurement and troubleshooting slower circuits. Its manufacturer-published limits—200 kHz analog bandwidth, a maximum real-time sampling rate of 1 MS/s and a 1024-point record—rule it out for RF, fast digital buses and detailed analysis of high-speed switching edges. Choose the kit if you want an assembly project and can solder and troubleshoot; choose an assembled unit or a more capable bench scope if you need a ready-to-use instrument or greater measurement capability.
What the DSO150 kit includes—and which version to choose
JYE Tech sells two DSO150 kit variants and an assembled version. The kit versions differ in the state of the analog board’s surface-mount components; neither includes a power supply. JYE Tech lists the standard BNC probe with the assembled unit, not with either kit.
| SKU | Format and analog-board SMD parts | Included accessories and manual |
|---|---|---|
| 15001K | Kit; analog-board SMD parts pre-soldered | One BNC-clip cable; English manual |
| 15002K | Kit; analog-board SMD parts not pre-soldered | One BNC-clip cable; English manual |
| 15001 | Assembled oscilloscope | Standard BNC probe; English/Chinese manual |
These package details and specifications are published on JYE Tech’s current DSO150 product page and legacy product page. If you want to build the unit but would rather avoid soldering the analog-board SMD parts, the 15001K reduces that part of the job; it does not turn the kit into a no-solder project. The 15002K leaves those components for the builder. A standard BNC 1x/10x oscilloscope probe is a useful optional accessory for either kit: the included clip lead is simpler, while the probe is a more conventional way to connect to a circuit. Hackaday’s 2017 reviewer also found the short clip lead less useful than a probe and reported using a standard 1x/10x probe (Hackaday review, 2017-11-09).
How capable is it for real measurements?
JYE Tech publishes the following specifications. They describe the instrument’s stated capabilities, not a guarantee of accuracy for every signal or setup.
#1 Best Overall
- Digital DIY oscilloscope uses ARM Cortex-M3 processor and contains a 2.4-inch color TFT display, which can be used as an ARM development test board.
- Let you effectively observe and measure signal waveforms in many occasions such as audio, video synchronization, low-frequency switching power supply, infrared receiving and transmitting.
- Can make a tailor-made software development on the basis of this kit, which can be can be changed to millivoltmeter, data recorder, etc.
- The variety of components is suitable for students to understand the oscilloscope structure and principles, and do in-line component , and chip component training.
- The oscilloscope kit is a kit specially designed for professional teaching and training in electronics. Please note that this kit need to be assembled by yourself.
| Specification | Manufacturer-published value |
|---|---|
| Channels | 1 |
| Analog bandwidth | 0–200 kHz |
| Maximum real-time sampling rate | 1 MS/s |
| Record length | 1024 points |
| Sensitivity | 5 mV/div to 20 V/div |
| Sensitivity error | Under 5% |
| Resolution | 12-bit |
| Input impedance | 1 MΩ |
| Maximum input | 50 V peak with an x1 probe |
| Coupling | DC, AC and ground |
| Timebase | 10 µs/div to 500 s/div |
| Trigger | Auto, normal and single; rising- or falling-edge; fixed at half the buffer |
| Display | 2.4-inch, 320 × 240 color TFT LCD |
All values in the table are from JYE Tech’s current product specifications. The single channel means you cannot compare two signals simultaneously, and the 1024-point record is short by the standards of scopes designed for detailed capture and analysis. A maximum input of 50 V peak applies with an x1 probe; do not treat it as a safe limit for every probe setting or connection. Check the probe’s attenuation and rating, as well as the circuit voltage, before connecting it.
The bandwidth and sampling figures are most useful as boundaries for choosing a task. The DSO150 is a reasonable fit for basic waveform learning and slower, low-frequency troubleshooting. It is not a suitable choice for RF work, fast buses or detailed high-speed switching-edge analysis. Its published minimum timebase is 10 µs/div, another practical limit when looking at short events.
Rank #2
- DSO 150 kit is an upgrade to the popular DSO138 scope kit. Contains a 2.4"""" color TFT LCD (320x240) display and optical encoder for navigation.
- Auto/normal/single trigger modes, easy to capture the moment waveform. use 9V DC power charger (NOT Included).
- Convenient to capture the instantaneous waveform. 2.4-inch color TFT display, waveform parameter digital display include: Frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values and effective value. with secondary development on the basis, can be changed to voltmeter, data loggers.
- Used for secondary development on the basis of this kit, it can be changed to millivoltmeter, data loggers with instructions, easy to install and operate.
- waveform storage function: waveform will not lose when save/tune out the waveform/shutdown waveform, available rising or falling edge trigger, observable previous waveform before trigger (negative delay), can freeze waveform display at any time (HOLD function).
Hackaday’s reviewer reported in 2017 that a signal-generator check showed the displayed amplitude tailing off above the claimed 200 kHz bandwidth and described the claim as “pretty spot-on.” That is the reviewer’s observation from that article, not a current independent lab test or a promise of measurement accuracy (Hackaday, 2017-11-09).
Is the DSO150 good enough for a beginner?
It can be a useful beginner instrument if the goal is to learn what an oscilloscope does while building a modest, limited scope. It is less appropriate as a first choice for someone who needs dependable, broad-purpose bench measurements or expects the kit to assemble itself. JYE Tech says builders should have adequate soldering and troubleshooting skills and explicitly cautions: “It is not guaranteed that you will end up with a working device.” (JYE Tech, DSO150 product page.)
Rank #3
- This DSO 138 oscilloscope circuit boards has been assembled and can be used directly.
- This oscilloscope board uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.Can freeze at any time waveform display (HOLD function).Comes 1Hz /3.3V square wave test signal source.
- 2.4" Oscilloscope with automatic, regular and one-shot modes, easy to capture the moment waveform.Available rising or falling edge trigger.Observable previous trigger waveform (negative delay).
- 2.4 inch TFT handheld pocket-size digital oscilloscope with waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.Waveform storage function: will not lose the waveform after power off.
- Partially open-sourced,the MCU has been programmed, adjustable vertical displacement,and with instructions,which increase the likelihood of adding different features or developing new applications on the hardware for users.
The assembly burden depends partly on the SKU. The 15001K arrives with analog-board SMD parts pre-soldered; the 15002K does not. In either case, assembly and fault-finding still call for care and basic electronics skills. The official assembly guide’s indexed tool list includes a flush cutter, tweezers, a 20–25 W iron for most components, a higher-power iron for the BNC connector, rosin solder, a multimeter, screwdrivers, pliers and a suitable supply. Treat that list as a guide to preparation, and consult the official DSO150 user manual and assembly guide for the exact instructions.
Hackaday’s 2017 account describes powering the main board to check the display, fitting through-hole components, assembling the encoder and case, checking voltages, using the clip lead with the calibration output, and adjusting compensation capacitors before closing the case. That is one reviewer’s build sequence, not a guarantee that every kit or assembly will follow the same path (Hackaday, 2017-11-09).

What power supply does the DSO150 need?
For the kit, use a 9 V DC supply with a standard 5.5 × 2.1 mm plug. JYE Tech specifies 8–10 V as the acceptable range, warns not to exceed 10 V on the kit, and lists 120 mA at 9 V. The assembly manual’s indexed text calls for a 9 V supply rated at 200 mA or higher. Check the adapter’s polarity and plug suitability before connecting it; the kit does not include a supply. Do not apply the assembled-version 15 V allowance to a kit.

JYE Tech dates an analog-board change for the assembled DSO150 to 2022-11-07. The company describes the updated assembled board as more tolerant of supply voltage up to 15 V and as correcting distortion on large negative signals. It also says that change requires new firmware and is not implemented in the kit because of space constraints. Kit owners should follow the kit’s 8–10 V supply guidance rather than infer that the assembled revision’s higher tolerance applies to their unit (JYE Tech product page).

JYE Tech warns that counterfeit DSO Shell products exist and offers a product-ID genuineness check. The manufacturer identifies PIDs “t2uvGy8a” and “eZn6IX2r” as fakes, which it says may not be firmware-upgradable or supported. Use the company’s product-ID check and authenticity information if you need to verify a unit; the warning does not establish what proportion of listings or units are counterfeit.
Who should buy it?
- Consider the kit if you want a soldering and electronics-learning project, can troubleshoot a build, and mainly need to inspect slower, simpler signals.
- Consider the assembled SKU if you want to avoid the kit assembly process and prefer the package that JYE Tech lists with a standard BNC probe.
- Look for a more capable bench oscilloscope if your work needs more than one channel, greater bandwidth, faster sampling, longer capture records or closer analysis of fast transitions.
- Verify any listing against JYE Tech’s genuineness guidance before relying on the product’s support or firmware options.
JYE Tech links official materials including the Version E/F analog-board user manual, schematics, firmware, upgrade directions, troubleshooting FAQ, source code and a DSO150 library document from its product page. The library document outlines a signal path from input conditioning through ADC sampling and a sample buffer to display capture, and explains that its coupling function changes an internal setting while actual coupling depends on the analog-board switch (JYE Tech, “How to Use DSO150 Library”).
