ELEGOO ELEGOO for Arduino Nano V3.0, Nano Board CH340/ATmega328P Without USB Cable, Compatible with Arduino Nano V3.0 (Nano x 3 Without Cable)

He visto que algunas copias de Arduino Nano tienen problemas con el pin VIN, pero este funciona perfecto.

Product received as described. High Recommended.

What a great value - 3 nano boards for basically $5 each. It's a real ATmega chip, and even though the USB driver chip is not the more-ubiquitous FT brand, drivers are not needed in 2021. I love that it's a tiny arduino-compatible board that is very inexpensive and has only what I need to make a project out of it - no pin headers, just a USB connector, the basic LEDs, and through-holes. The unregulated power input is awesome (standard for nano style), I can just connect it to a 12v DC wall adapter that the rest of my project is already using. It's got a bunch of digital and analog ports, including 6 pulse-width modulation ports. I'm just getting back into Arduino, so this is probably pretty standard stuff, but it's cool to see so much potential in a tiny computer that is now the least-expensive part of almost project. 2021 update for Macs using Big Sur - it works out of the box now. Don't install any extra drivers, just connect it and install Arduino IDE 1.8.3 (marked experimental version). In Arduino IDE, set Board to "Arduino AVR Boards > Arduino Nano" and for Processor choose "ATmega328P". For Port, choose the one that starts with "/dev/cu.usbserial" or "dev/tty.usbserial" and then you're good to go. My only complaint about this board is the USB mini style connector. It would be nice to see micro USB or even USB-C, but it's a really minor thing - cables are not expensive and most of us have an old USB mini cable collecting dust somewhere.

I ordered two sets (six Nanos). All tested perfectly. For MAC, use the web address on the order page and download the NANO files, the serial driver will be in that package. It won't be recognized in your Arduino IDE otherwise. Simple process to download and unzip and execute. Restart and you now have a port you can work with in the IDE. Choose Arduino Nano and make sure the AT mega328P processor is selected so you can talk to the boot loader successfully. The download package has all the instructions, it's very easy and worked just as they said it would on my MAC. I tested all six in the following manner: plug in and ensure l13 is blinking (comes preloaded with "Blink"). load program of your own choosing and check to see if it works (program should activate l13 and interact with serial console) press reset button to make sure the Nano reset button works reload Blink and check Boom - you have an awesome $4.26 Arduino ready to do great things for you. Again all of mine tested perfectly. You have to solder the headers in and the space is limited so be careful. Not the best platform for prototyping but, once you've figured out what you want your Arduino to do, these are my main "deployment" Arduino platforms. Cost efficient (They're a steal) and very space saving. I highly recommend for trouble free, super inexpensive Arduino deployment. UPDATE: I ordered six more nanos, performed the same test as above and all tested perfectly. I'm stocking up while they are inexpensive. The quality consistency of this particular product is excellent. I have had one nano blinking for two weeks now nonstop. Just checking to see if it dies but it just keeps going and going and going...

I used this in my 3d printed Iron Man helmet to control servo motors for the face mask and eye lights. Works as an amazing and cheap replacement for the Arduino Nano as long as you don't plan on using as much processing power
