Emakefun Nano-Micro-Nosolder for Nano V3.0, Micro USB Nano Board ATmega328P 5V 16M Micro-Controller Board

Worked well once settings in IDE were all set.Ensure you have the driver installed and that your cable is good. I have so many cables around I tend to some how always grab one that is only for charging. I have to then test it on something I know worked in the past. And with all the negative reviews, ones first thought is that it must be the board.Nope.. once was sure I had a good cable and set the proper board and Processor (also called boot loader a lot) it was all good from there.See image alsoBoard is "Arduino Nano"Processor: "ATmega328P(Old Bootloader)"This is a well priced, quality board.* Price speaks for it self, ~$5 each delivered.* See the images for the quality of the board.I will buy more when I need them. You should buy with confidence.

This is a review of the Emake Fun Arduino Nano compatible board. To be clear, it is a clone of a "real" Arduino. For 5 for around $20, this is 1/5 the price of an Arduino directly from store.arduino.cc.First, if you want to use this on a breadboard you'll need to solder on the included headers. This is fairly straightforward but in my excitement I ended up with an off-by-one error when I did the first header. After desoldering and correcrlt aligning the pins, I attached it to my PC. It showed up immediately on my /dev/ttyUSB0 port. I added myself to the dialout group, then fired up the Arduino IDE. I chose the Arduino Nano board with the Atmel 328, loaded the example "Blink" sketch, compiled, then uploaded. It worked immediately. Next, I tested the serial output examples and these worked as expected.I do feel a little guilty for not buying genuine Arduino all the time, but I go through so many of these that it would be cost-prohibitive otherwise.Nothing much else to say about these. They work for my sketches (mostly reading MQ sensors and driving stepper motors and relays). The Micro-USB connector is a great convenience.

The above comments about usability and compatibility are spot on. Also, the price is unbeatable. Another thing I noticed is that they are relatively indestructible. These were the first boards I bought, and only assembled three. Since then, I have bought 12 3.3 volt boards...and have smoked 4 (so far). It was my carelessness, but the first three of these Emakefun Nanos are still going strong. I have put them in various projects, hooked up all kinds of relays and sensors, and they continue to work. I'm glad I bought them.

As others have said, these work great if you take a few extra steps.Here they are in a concise form for Windows 10:1) Download CH340 drivers. You can find these in many places. I got mine from https://sparks.gogo.co.nz/ch340.html2) Connect the device with a microUSB cable3) Find "Ports (COM & LPT)". In that category, find the Nano. Mine showed up as "RAMPS". If you have other stuff there, just unplug and replug the nano and see what shows up.4) Right-click the device and choose "update driver"5) Choose "Browse my computer..."6) Choose "Let me pick from a list..."7) The CH340 driver should be an option on the list that appears. Mine shows as "USB-SERIAL CH340"8) In the Arduino IDEuse the Aruino Nano board with the ATMega328P bootloader. All mine use this bootloader, not the old one, but some people say the old one works for them.and, if you're like me:9) You're saving a lot with these boards. Please donate to Arduino.cc a few bucks because you're using their software with a knock-off board and they deserve a little love too. The savings make it worth it.

I mainly bought these because of the micro-usb interface, because obviously we have more of those cables laying around than any other... but after using these for a couple of months now, I can't say that I would buy them again.The fact that they have the old boot loader isn't a big deal, as you can flash them to the new boot loader with a usbasp card like this one https://www.amazon.com/HiLetgo-ATMEGA8-Programmer-USBasp-Cable/dp/B00AX4WQ00/ref=sr_1_1?keywords=usbasp&qid=1557912518&s=gateway&sr=8-1.The main issue i've had with these are that a few of them - for no reason - lost the ability to communicate over USB, so I have to program them with the usbasp card which does work, but then to interact with the running program, I have to use software serial and a separate serial card. Which is really an inconvenience.I've been working with Arduino's for a few years now, and I've never seen them arbitrarily loose their USB capability. perhaps just luck of the draw, or cheap component choice on their part, these things just have an overall feeling of "clunky" and inconsistent to me ...If you aren't totally hooked on the micro-usb connector, I recommend going with a more solid Nano ... I've had good luck with these before: https://www.amazon.com/gp/product/B07D12TWNZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1*** Update 6/8/19 ***Only one left with a working USB port ... I definitely will not buy these again... downgraded from 3 stars to 1 because only one works properly now .. its a shame really.

My package arrived yesterday and I had the first one programmed and running in about 10 minutes. My main machine is a MacBook Pro, and I learned that Mac OS has had driver support for the CH340 built in to the OS since Mojave. I am running Catalina, and sure enough the board connected on the first try.The only "gotcha" was that the Arduino IDE could not upload to the board when I had it set to Arduino Nano. I read a comment here that said to put the IDE on Ardunio Duemilanove, so I tried that. It worked on the first try, and my little sketch is running perfectly on the board right now.So overall, maybe a little more hassle to program than an official Nano, but at $3.50 per board I am OK with this.BTW these came with the pin headers NOT soldered on, which is exactly what I wanted.
