• This DSO 138 oscilloscope circuit boards has been assembled and can be used directly.
• This oscilloscope board uses ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display screen, can be used as ARM test development board.Can freeze at any time waveform display (HOLD function).Comes 1Hz /3.3V square wave test signal source.
• 2.4" Oscilloscope with automatic, regular and one-shot modes, easy to capture the moment waveform.Available rising or falling edge trigger.Observable previous trigger waveform (negative delay).
• 2.4 inch TFT handheld pocket-size digital oscilloscope with waveform parameter digital display, including frequency, period, pulse width, duty ratio, MAX./MIN./AVG./Peak-Peak/virtual values.Waveform storage function: will not lose the waveform after power off.
• Partially open-sourced,the MCU has been programmed, adjustable vertical displacement,and with instructions,which increase the likelihood of adding different features or developing new applications on the hardware for users.
