Il mini oscilloscopio 4 in 1 che sta in un taschino 📏

In this video, we'll analyze an incredible 4-in-1 mini oscilloscope from Zoyi, a device so compact it literally fits in a pocket! Despite its size, it offers oscilloscope functions (10 MHz), function generator, MCU programmer, and DAPlink for debugging ARM chips. We'll unbox it, explore its technical features, and perform an in-depth test comparing it with professional instruments (Tektronix and HP) and its bigger brother, the Zoyi 703. I'll also explain the basics for beginners: how to adjust the vertical and horizontal axis, and how to properly use the trigger to freeze waveforms. Finally, I'll disassemble it to see what's inside!
