Features: This digital oscilloscope kit uses ARM CortexM3 processor and with a 2.4-inch TFT screen. It is simple and reliable for circuit operation. It can display frequency, period, pulse width, working conditions, etc. This kit uses CortexM3 processor (STM32F103C8), and includes a 2.4-inch TFT color 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, data loggers. With automatic, normal and One shot modes, it is easy to capture the waveform. Can freeze at any time waveform display (HOLD function). Comes with 1Hz /3.3V square wave signal source. Waveform storage function: will not lose the waveform after power off. Short circuit and open circuit detection: can help the user find the soldering error. TFT controller recognition function.
