Features:
This is welded (assembled) and can be used directly.
Used for audio, video synchronization, low-frequency switching power supply, infrared transmission and reception signal waveforms, etc., for effective observation and measurement.
Adopts the Cortex-M3 processor (STM32F103C8) and includes a 2.4-inch color TFT display that can be used as an ARM development test board.
Can be developed twice according to capabilities, for example, it can be changed to a millivolt table, a data logger, and the like.
Simple, reliable and inexpensive circuit.
Automatic, regular and single trigger mode for easy capture of instantaneous waveforms.
Trigger with rising or falling edges.
Trigger level position adjustable with indication.
Observe the waveform before the trigger (negative delay). 
The waveform display can be hold at any time (HOLD function).
Self-contained 1KHz / 3.3V square wave test signal source.
With waveform parameter digital display, the parameters that can be displayed are: frequency, period, pulse width, duty ratio, maximum value, minimum value, average value, top-to-top value, effective value.
Save/recall waveform, shutdown waveform does not disappear.
Vertical displacement adjustable with indication.

Specification:
Maximum real-time sampling rate:1 Msps
Accuracy: 12Bit
Sample buffer depth: 1024 bytes
Analog bandwidth: 0 - 200KHz
Vertical sensitivity: 10mV/Div - 5V/Div (inward by 1-2-5)
Input impedance: 1MΩ
Maximum input voltage: 50Vpp (1:1 probe), 400Vpp (10:1 probe)
Coupling methods include: DC/AC/GND
Horizontal time base range: 10μs/Div -50s/Div (inward by 1-2-5)

Package List:
1 x Digital Oscilloscope
1 x B1 Probe
1 x Users Manual
Users Manual:
To turn on/off the waveform parameter display: Place the cursor at the time base position and press and hold the (OK) key.
To save the waveform: Press the (SEL) and (+) keys simultaneously.
To recall a saved waveform: Press the (SEL) and (-) buttons simultaneously.
To enter the test mode: press and hold (OK) and then press the (RESET) key. If you see the LED flashing rapidly, it means that the PB or PC port of the MCU (these port contain the connection with the LCD) is short-circuited. After removal, if you see the LED flashing in a period of about 4 seconds, you can use the voltmeter to find possible open circuit
