Small oscilloscope used in development (Patreon)

Here is an introduction to a small oscilloscope that frequently appears in my YouTube videos.

I use an oscilloscope called seeed DSO Nano V3.

It is USB rechargeable and can measure one channel of voltage.

The input of the probe is a 3.5mm mono plug, so you can simply connect a patch cable to read the signal.

I bought it from a distributor in China for $60.
