Features:1. This kit uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.2. Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.3. Adjustable vertical displacement, and with instructions.4. With automatic, regular and one-shot modes, easy to capture the moment waveform.5. Available rising or falling edge trigger.6. Observable previous trigger waveform (negative delay).7. Can freeze at any time waveform display (HOLD function).8. Come 1Hz /3.3V square wave test signal source.9. With waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.10. Waveform storage function: will not lose the waveform after power off.11. Short-circuit and open-circuit detection: can help the user find out the soldering error.12. TFT controller recognition function. Note:This DIY kit is soldered. Specifications:1. Maximum Real-time Sampling Rate: 1Msps2. Accuracy: 12Bit3. Sampling Buffer Depth: 1024 bytes4.
