Training for electronic production, complete detailed descriptive information, including schemas, production guides, instructions, problem-solving methods, etc., make for a high success rate.Variety of component species for students to identify elements, inline elements welding, SMD soldering component training.The kit uses an ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display that can be used as a test arm development board.Available resources, partner capabilities can be a secondary development kit based on, for example, it can be converted to Millivoltmeter, data, and so on.The circuit is simple, reliable, value for money. input: DC 9V ( adapter not included)Maximum real -time sampling rate: 1MspsAccuracy: 12BitSampling buffer depth: 1024 bytesAnalog bandwidth: 0 -200KHzVertical sensitivity: 10mV/Div -5V/Div (1-2-5 way)Adjustable vertical displacement, and with instructionsInput Impedance: 1MMaximum input voltage: 50Vpp (1: 1 probe), 400Vpp (10: 1 probe)Coupling modes include DC/AC/GNDHorizontal time base range: 10 s/Div-50s/Div (1-2-5 mode)With automatic, normal and one -shot modes, it's easy to capture time waveformsThere is an increase or a fall edge triggerAdjustable trigger level position, and with instructionsTrigger waveform due to previous (negative delay)Can freeze at any time waveform display (holding function)Comes 1Hz /3.3V square wave sourceColour: redMaterial: PC+metalPackage Contents:1 * Soldered 2.4 Inch TFT Digital OscilloscopeOnly 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 is +/- 1-3cm.
