Nano V3.0, Nano Board ATmega328P 5V 16M Micro-Controller Board Compatible with Arduino IDE (Nano x 3 with USB Cable)

I've been using these while getting deeper into microcontroller projects, and I've become a big fan of these little Nano boards. They're not the newest or most powerful microcontrollers around, but that's really not the point. Sometimes I don't need Wi-Fi, Bluetooth, a ton of memory or a powerful processor. I just need something inexpensive with enough I/O to read some sensors, control something, or handle a simple dedicated job. That's where these shine. I've programmed mine through the Arduino IDE and have used them for actual electronics experiments, not just a blink test. They've been reliable for me and the small size makes them easy to work into projects. I especially like buying them in a multipack. At this price I don't feel like I have to keep stealing the same development board back out of one project every time I want to build another one. I can just leave a Nano in it. If you're learning Arduino, prototyping circuits, or building projects where you don't need the additional features of something like an ESP32 or Pico W, these are extremely useful little boards. I'll almost certainly be buying more.

First attempt at downloading was unsuccessful. I was using an older version of the Arduino IDE (1.0.5) on a Raspberry PI 4. I was powering the Nano via the USB port. The USB to serial chip was instantly recognized and provided a serial port to use. Almost all Arduino clones are using the CH340G device. I was getting a "programmer not responding error" every time I tried to upload. The webs were recommending to use Old Bootloader setting, but I did not have that as an available option. I downloaded the latest Arduino IDE forLinux 32-bit from arduino.cc and installed it. I first tried to reproduce my original error using Board: Nano, Processor: 328P, and Programmer: Arduino as ISP, but it worked the first time using the latest Arduino IDE(1.8.7?). I received my Nano boards February 14, 2020. I do not know if I have the new bootloader or the old one, but I know that I DID NOT have to select the old one under Processors. Even if you do have the old bootloader, you could always update it if it is an issue. I am very happy with my purchase. The visual quality is as good as I could ask for at any price. I think there may have been some flux residue around the programming header, but if that's all I can complain about then they must be pretty good. Each Nano was individually boxed.

There is a lot of garbage on amzn. These boards have lived up to their claims. I just purchased 6 more and they are quality!

Very good, consistent build quality on all three Nanos and their cables. All 3 worked (almost) out of the box using the current standard "ATMega328P" Processor selection under the tools menu, rather than the "ATMega328P (Old Bootloader)" selection some reviewers have mentioned here. The CH340 chip was recognized automatically in Windows 10 Professional that I installed on a new system about 18 months ago. The CH340 driver came as part of the Windows system. I did have one very odd experience though, which may or may not have something to do with my having initially selected the "ATMega328P (Old Bootloader)" processor for my first program upload attempt. I was running Arduino 1.8.12, which I had downloaded off the Arduino site. Shortly after that initial failed programming attempt (using the Old Bootloader), I got a message from Windows asking me to approve a Java Update. I assumed this was just a coincidence. I accepted. Not long afterward the Arduino IDE simply disappeared off the screen. When I restarted Arduino, I discovered I was now running Arduino 1.8.33 which can only come from the Windows App Store. Problem is, I had never downloaded that version, at least not on purpose! And from then on, any attempt to load the Arduino IDE would display the splash screen for a few seconds, and then quit. Have yet to find a really satisfactory solution to that, although there is an awkward word around. Hoping for a fix next iteration. Meanwhile I'm awkwardly back to 1.8.12. Weird, huh? I don't know if it's fair to peg the Nanos with this, but who knows. Did using the old bootloader crash the system, and was Windows just trying to save the day? Or to get more paranoid, was there some tricky bit of software in the Nano itself? Would like to hear from anybody else with this experience. I just hate it when others try to save me from myself without first asking. But putting paranoia aside, these LAFVIN Nanos are working great. For most users they should be able to handle a big percentage of more or less "normal" applications. And the low price makes them a good choice for ham-fisted, static-charged kids not known for careful handling. The only real downside for me is that there is no built in Midi support, so if you're a musically inclined hacker something like a Teensy LC would be a much better choice. I do so love my LC powered, CC1 modulation wheel pedal. PS To be clear the newest ATMega328P processor choice under the TOOLS menu item is the one you should try first, not the one labeled as the "Old Bootloader."

Works Great.

Let me preface my review with one fact: I have only used one so far beyond simply plugging them in; all three are recognized with no issue. I will update this review should my milage vary with the other two. Three boards and three USB cables for the price is almost too good to be true. Upon arrival, I immediately got to work. Soldered one into a perfboard, wired in a molex connector, soldered in 8 3-pin ARGB headers, soldered in power lines and various filtering caps and resistors, soldered to 8 data pins with 330 ohm filtering resistors, and checked for shorts. Had one short on the power end of things considering how much wiring and components are packed in a 25x12 perfboard. When hooked up in situ, the board gets 12V which is the upper end of allowable input voltages. Works perfectly. All 8 outputs I used function as programmed. I used the basic setup as mentioned in other reviews in the Arduino ide, but the "old bootloader" didn't work for me. I just used the standard 328P. Board runs just fine with a 12V input. Totally satisfied. Makes great prototypes for an open source addressable LED controller utilizing The fast led library. I don't expect any issues when migrating to my standalone software.

In the Q&A section someone suggested googling "arduino nano CH340 driver" which I did. Found the drivers, after installing, the online Arduino IDE (with local windows 10 plugin) was able to detect the boards. Uploaded a quick blink + serial write back sketch, and it uploaded fine. The led is blinking, it's writing back to the serial port so I can read from within the IDE. For $14 for qty 3 this is an amazing value. I went with this one since it had the extra USB cables. I have bought the individual components from Arrow.com for the ATMEGA328P plus the 16Mhz crystal, and caps in order to cheaply deploy local projects. But, even that route with the quantity discounts where the atmega chip is $1-2 bucks, and the other parts are 10-50 cents, it still comes out to around $3 bucks and that doesn't include solder, time, or usb connector, or ftdi chip or even the pcb. Also, since I'm doing through-hole soldering, the atmega chip is nearly the size of this board. All things considered this board is much more compact than my $3 boarduino. When considering that, and needing to burn the bootloader on the raw atmega chips, compared to this is all completely done and ready to go. The extra $2 per unit is insanely cheap. Super stoked to have given these a try.

Works with simhub made a charm run off of lateral g force of the car

Funcionan perfectamente

Very bad The ardino in the pic is not same as sent,ur dealer & service is very bad .

Muy buena calidad. Gracias
