    DSO FNIRSI-138 Kit:

    • 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.

    • Can be secondary development on the basis of this kit, for example, it can be changed to Millivoltmeter, data loggers.

    • 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).

    • Can freeze at any time waveform display (HOLD function).

    • Comes 1Hz /3.3V square wave test signal source.

    • 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.

    • Short-circuit and open-circuit detection: can help the user find out the soldering error.

    • TFT controller recognition function.

    • The SMD has been soldered, more suitable for electronic beginner.
