FNIRSI-138 2.4" TFT Handheld Mini Digital Oscilloscope Kit + DIY Acrylic Shell

Features:

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.
