2.4" TFT Pocket Digital Oscilloscope Kit DIY Handheld Parts + Acrylic Case DIY Case for DSO138 OOTDTY 100% Brand New and High Quality Features:This kit uses ARM Cortex-M3 (STM32F103C8) processor and includes a 2.4 inch TFT color display, can be used as an ARM test development board. It can be a secondary development based on this set, for example, it can be changed to millivoltmeter, data loggers. Adjustable vertical displacement and instructions. With automatic, regular, and one-time modes, you can easily capture the waveform. Rising or falling trigger available. Observable previous trigger run (negative delay). It can freeze the waveform display at any time (HOLD function). The source of the 1Hz /3.3V square wave test signal is provided. With digital display of waveform parameters, including frequency, period, pulse width, operating ratio, MAX./MIN./AVG./Peak-Peak/virtual values. Waveform storage function: it will not lose waveform when power off. Short circuit and open circuit detection: it can help the user to find the soldering error. TFT controller recognition function. SMD has been soldered, more suitable for electronic beginner. Specification: DSO138 kit Type: non soldered DIY kit and if you are interested, you can find the other one in this store which SMD is soldered.
