ELEGOO Nano Boards V3.0, ATmega328P CH340, 3-Pack, Compatible with Arduino

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...

Review written 12/28/2018: I'm a complete Arduino newbie, with just one week with a standard UNO r3 under my belt, but I had no trouble getting these ELEGOO Nanos to work perfectly. Here's my experience: I downloaded the IDE a week ago from the Microsoft Store, and the installation was flawless. I've been using it about a week with my UNO and various sketches that I wrote, including one using the IR remote to command two types of servos. When I received the ELEGOO Nanos from Amazon and plugged one in, a compatible driver was found automatically by Windows 10. I verified this by going to Device Manager>>USB controllers, and there were no exclamation points. I then went to Device Manager>>View>>Show Hidden Devices, then Device Manager>>Ports. I saw an entry USB_SERIAL CH340 (COM4), which looked like the Nano. The Blink demo seemed to be already running. Then I went to IDE>>Tools>>Board and selected Arduino Nano. Then IDE>>Tools>>Processor and selected Old Bootloader. Then IDE>>Tools>>Ports and selected COM4. I loaded the sketch for Blink into the IDE and changed the on-time to 3 seconds, and hit the upload arrow. It worked as expected. Then I loaded my servo/IR remote sketch after rewiring to the Nano, and the program worked as expected with the smaller servo, but choked on the larger one. I changed the power supply to the servos (only) to a 4 AA cell battery pack, connected the grounds of the Nano and the AA cells, and both servos worked perfectly. ELEGOO must be shipping a better product now that what earlier reviewers had to suffer through. I learned from their hard work. Five stars for me... Pic shows a breadboard with UNO r3 (disconnected) and Nano on it, two servos, IR remote and battery box. LEGO train switches are now remotes. Grandson is happy!

As for the board: so far so good. Cheap, works as intended, an annoyance to setup as others have mentioned, and I'd rather have a micro USB, but overall I'm satisfied. One star off for the difficulty in setup (read on for how I got mine to work; it literally involved a random hunch), otherwise a good board for permanently embedding in a project as its small and inexpensive. ----- Instructions for use current as of 6/27/2020 ----- Just got one of my boards working. I was following the advice of other reviewers who mentioned you need to select Arduino Nano as your board and ATmega328P (Old Bootloader) as your processor. Turns out this might have worked in the past, or for particular people's setups, but it did not work for mine. Here's how I got things to function: First off, I'm using the 1.8.13 version of the Arduino IDE, which is the most current as of this review (6/27/2020). I can't guarantee this is what caused the issue, but I'm going to assume its part of it. I'm running Windows 10 Home, 64 bit, version 10.0.17134 Build 17134. Your mileage may vary if you are running a different version or a different OS entirely. When I initially plugged the nano into my computer, I could not see any COM port appear. I had already installed the CH340 drivers (you can do so from elegoo.com/download, or from Sparkfun at https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all). Turns out my first mistake was a simple one: I didn't use a data cable. The cable I found lying around turned out to be for power only. Keep this in mind. The way you can tell is if the Nano starts running the LED blink program, but is not discovered by your computer. The blink program will run as it comes preloaded so it will run when the board is powered on. This means either you have a power-only cable, or somehow the data pins have been damaged (less likely that only those pins specifically would be damaged, but who knows... its possible). Switching out the cable fixed the discovery issue. I still couldn't upload to the board though. Once the board was discoverable, I then began following video instructions from the Sparkfun page I linked to above. They said to re-run the CH340 driver executable, uninstall the drivers, then reinstall them. This time I got a message saying the drivers had been installed correctly, rather than having been "pre-installed" as was mentioned before. I tried uploading again, but no luck. Still, the drivers do need to be installed correctly so this was probably a secondary issue. Who knows, but I'm going with that. I could now see a new populated COM port, so I knew the Nano was being seen now. I once again set my IDE settings to Arduino Nano as the board, ATmega328P (Old Bootloader) as the processor, and finally the new COM port as the port. Still nothing. As a last ditch effort, I tried switching the board to Arduino Uno. "Done uploading." What do you know... it worked. Why? Who knows... but it did. I hope this helps somebody else out with this odd situation.

I purchased these for a variety of projects - they have all the pins you need for most things D2 thru D13, A0 thru A7. I am currently using on I2C with a clock and 4 x 20 display, with alarms, 4 Ultrasonic Sensors, 3 switches, 2 relays... and have pins left over (of course I2C saves a lot of pins). I'd recommend these tiny boards instead of regular large form factor Arduino Uno boards for most applications (unless stacking shields is important to you) - I never have 'too much' space for my projects! There are even smaller boards but I like all the pins to be available and the USB connection - it makes programming easier without a special 'header' and also powering option via USB for final project. And this is so small as it is, it's tough to justify a smaller board by losing those features imho unless you are really strapped for space. With Arduino IDE software (I'm on 1.6.8) be sure to choose "Arduino Nano", "ATmega328" and proper COM port, and with a usb cord you are good to go. Pros: work well, small size, unsoldered connectors (gives you options) Cons: no documentation at all (however these are ez to use)

Short version: Do not use the Arduino “ Windows app Requires Win 8.1 or 10” With this version you will not be able to “talk” to the Nano and you will not be able to upload your code. Make sure you are using "Windows Installer, for Windows XP and up" (version 1.8.5) from the Arduino site. Both of the above versions can be found on the IDE site. Long version: When I received my 3 Nano’s (this was the first time I tried a “off brand”) the first thing I did was plug them in to USB power to check if “blink” was working, sure enough all 3 worked and all 3 showed that they were connected to a com port. I did not even have to install the USB drivers. Life is good…..I thought. I had just install this test desktop a month ago and every "real" board I tried worked perfect. Then I tried to upload a sketch. All I got was errors saying that the IDE could not “talk” to the nano. I thought OK, I do need the USB drivers so I installed them. Still no joy, I tried everything.. Different USB cables, changing the setting in the IDE, removing the USB driver, trying all 3 boards, but nothing would work. I then decided to reinstall the Arduion IDE, That is when I noticed the two version of the IDE for windows. I have installed the IDE tons of time in the past and uploaded 100’s of sketches but never noticed the “window app” before. I install version 1.8.5 of the IDE and everything just started working. So If you are getting errors uploading with these boards just make sure to check the version of the IDE. If it does not show 1.8.5, remove it and install 1.8.5.

I needed an interface between Windows 10 and my universal remote program jack. The software program from the JP1 site recommended using a Nano board and provided the Nano sketch. I purchased the ELEGOO brand based on the Amazon reviews. They arrived on time, and I downloaded the instruction manual from the Amazon page. per the instructions, I downloaded and installed the Arduino program on my Windows 10 desktop. I connected one of the Nanos to a USB port and the Arduino program recognized it immediately without installing the ELEGOO driver. The Sketch loaded without problems and the interface works. The only issue is that I didn't realize how tiny the Nano is. Soldering the connections was challenging but I have a very fine point soldering iron and decades of experience. For those not experienced with soldering very small connections I recommend buying units with the jumper pins already soldered on the board.

All three Nanos worked as expected. Nicely packaged.

Product received as described. High Recommended.

Fonctionne très bien.

De buena calidad y buen precio

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

Great boards compatible with all Arduino projects . These boards are very well made and are inexpensive
