I’m planning to build a few small IoT and robotics prototypes and am considering using the Arduino NANO V3.0 CH340 ATMEGA328P because of its compact size and multiple I/O options.

Has anyone used this board for projects like wearable devices, automation gadgets, or simple robotics?
I’m particularly curious about:

Any quirks when programming it with the Arduino IDE

Powering it via USB versus an external battery

Reliability of the CH340 USB interface compared to other Nano variants

I’d appreciate hearing about your experiences, tips, or common issues to watch out for when using this board in hands-on projects.

You understand that the volume of data you're requesting is enormous, right? And it's impossible to describe it all in a single message?

It will be much better if you describe the specific problems that arise, which can then be solved specifically.

For now, your question can be answered in general terms: such modules can be used. They will work. However, it would be much more appropriate to use individual microcontrollers and the hardware around them rather than entire modules.

Для макетирования/прототипирования вполне.
