Nano [A000005] - Compact ATmega328P Microcontroller with 22 Digital I/O Pins, 8 Analog Inputs, USB Connectivity, and Arduino IDE Compatibility for Prototyping and DIY Projects

I mounted this little wonder onto a small bread board, see jpg. I used the design from “30 Arduino Projects for the Evil Genius”, by; Simon Mork, in chapter #3, Morse Code Flasher. The design & C coding worked! The extended pins on the Nano helps in placing the Nano on to the breadboard and makes placement and soldering easier, see jpg. If you are doing Arduino Nano projects this is a great product to buy. My Nano is doing a great job of translating and flashing code.

Needed this for a project and it worked so well we're using it in another.

The Arduino Nano is exactly what it’s always been: a compact, reliable ATmega328P board that just works. If you need something small but fully capable for prototyping, this is still one of the best options out there. It has plenty of I/O for its size, works seamlessly with the Arduino IDE, and is easy to integrate into breadboards or permanent projects. USB connectivity is straightforward, and it’s been rock-solid for programming and debugging. No weird behavior, no random disconnects, no surprises. This is especially useful when space matters or when you want something simple and proven without jumping into more complex boards. It’s also great for quick experiments, embedded projects, and DIY builds where you don’t want unnecessary overhead. Nothing flashy — just a dependable microcontroller that’s earned its reputation over time. It's also a great value

Worth every penny. Incredible useful for rapid prototyping. If you know C++ or have electrical engineering background you’ll be coding and building projects within a few hrs. Hides most of the microcontroller abstractions in useful arduino built in functions.

Worked very well for my project. I used it by plugging it into the 2 sides of a breadboard. It is a little bit of a struggle to get into the breadboard, but that's normal. I checked and it was the same price on the actual site, so I just got it from amazon for faster shipping. Unfortunately, it doesn't come with the cable, so I had to buy 2 from amazon (USB A to USB mini) which is crazy because this little microcontroller is already expensive as is, but that's not amazon's fault.

Is good for what you are using for but you have to now what you are doing

Works great.

Most of the non-Arduino versions of this product requires you to locate, download and install the CH340 driver. Instead, the Arduino version uses the FT232 driver. Everything is pre-installed and ready to use, right out of the box. I had it up and running in minutes. In fact, in a networking project I'm playing with, it outperformed my other microcontrolers, including a couple of larger Arduinos. If I can find the time, i will deal with the clones and their CH340 driver.
