Features: This digital oscilloscope kit adopts ARM CortexM3 processor and with 2.4-inch TFT screen. It's easy and reliable for circuit operation. It can display frequency, period, pulse width, duty ratios etc This kit uses CortexM3 processor (STM32F103C8), and includes a 2.4inch color TFT display screen, can be used asARM test development board. Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, dataloggers. With automatic, regular and One shot modes, easy to capture the waveform Can freeze at any time waveform display (HOLD function). Comes 1Hz /3.3V squarewave signal source. Waveform storage function: will not lose the waveform after power off. Short-circuit and open-circuit detection: can help the user find out the soldering error. TFT controller recognition function.
