This kit uses ARM -M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board. Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, With automatic, regular and one-shot modes, easy to capture the moment waveform. Comes 1Hz /3.3V square wave source. With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./-<br><br>Maximum real-time sampling rate: 1Msps Accuracy: 12Bit Sample buffer depth: 1024 bytes Analog Bandwidth: 0 - 200KHz Vertical Sensitivity: 10mV/ - 5V/ (in 1-2-5 increments) Adjustable vertical displacement with indication 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/ - 50s/ (in 1-2-5 increments) With automatic, conventional and single trigger modes, it is convenient to capture instantaneous waveforms Trigger with rising or falling edge Adjustable trigger level position with indication Waveform before trigger can be observed (negative delay) Waveform display can be freeze at any time (HOLD function) Comes with 1KHz /3.3V square wave source Digital display with waveform parameters, the parameters that can be displayed are: frequency, period, pulse width, duty cycle, maximum value, minimum value, average value, -to- value, RMS Save/recall the waveform, the waveform does not disappear when power off Colour:Red Material:ABS Size:18 x 12.5 x 3cm<br><br>Package Contents: 1 * DIY Digital Oscilloscope Kit 1 * Probe<br><br>Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error i
