I needed a single nano board for a project I was building. I purchased this three pack because of the price and availability.  One out of the three was DOA when I plugged it into my computer to upload the firmware. Not a big deal for me as I only needed one and still have one left over.

I am using these boards for IOT projects using node-red. I have them running a dht22 sensor sending the data to a mqtt server with OTA updating. Great stuff for the price, I am using arduino IDE.

Currently working on a project to make a Proof of Concept Autopilot with an arduino board. Basically, to make an autopilot you need four things:

1.) Magnetometer (Compass, to determine heading)
2.) Accelerometer (To determine roll in relation to gravity)
3.) Barometer (Altimeter, uses pressure to determine altitude)
4.) GPS (To determine location)

I obviously wasn't going to find an all in one package for all of this - when I went window shopping for sensors I looked for all of them separately. I was obviously stressing about how I was going to solder a bunch of things and also custom make hookups for the I2C ports. Then, I came across this. It was really impressive how this fit 3 of the 4 things in one single board (And tiny as well!), saved me a bunch of headaches so I decided to jump in for it. The moment I first opened the package I was impressed - mind you I'm usually the aerodynamics guy for our projects so I don't get to fiddle with these a lot, but this was amazing. Last time I used a sensor, it was the famous ADXL345 board that just contained an accelerometer. This board, as you can see in the pictures, is smaller, and still includes two more sensors on board. Amazing!

For the actual product, I used a couple sample codes that I found lying around. The board does come with sample code as well, with the user manual for both the MPU-9250 and BMP-280 (Registries and everything), with the link to the .zip written on the little static proof baggie it comes in. Just four wires connecting SDA, SCL, 3.3V, and GND and I was in business.

The chips used in this, the MPU-9250 and BMP280 are both famous as well, so you will find a lot of support online. Adafruit has codes and writeups on the BMP280, as well as libraries, and Sparkfun has the same for the mpu-9250. I have a full on user manual on my blog at Uavtarik.blogspot . com for this specific board.

You might come across a problem with the BMP280 board if you're using the Adafruit libraries, with the code saying that the BMP board is not connected properly. Apparently, the Adafruit ones come with 0x77 I2C address, and some of the ones around here come with 0x76. Bosch apparently messed up during manufacturing? Just change one line of code noting the address in the BMP280 adafruit library and you're set.

The barometer calculates altitude, and finds temperature and etc very accurately, and the accelerometer is also very accurate. Moreso than the ADXL345 that I was using a while back. Heading and everything else with the Magnetometer is also perfect. This chip is a great idea if you're going to be making a weather station, autopilot for a drone (like me!), self driving car, so on so forth. Great tiny little board, I love it.

This motherboard works perfectly for what I need it for. I used it to build a FreeNas build in a mini ITX case. Can't really complain about it, as it fits my needs perfectly. All I really needed was a cheaper board with a CPU, and the size. Love it! The price is low, and the quality is great!

I bought this just to try and fix my son's tablet,  He managed to disconnect the battery from the motherboard.  I was able to solder the wire back to the motherboard with this little kit.  It worked perfect for my needs and the cost was great.

This is a great little board.  I used it to replace the motherboard in an ancient Via EPIA system which was quite slow in comparison.  When I need another small system I'll definitely think of this.

Lots of fun for a small little project, the tiny pieces are killer but they are nanoblocks :D I managed to piece it together and have a momentary panic before I found the line saying that there are extra pieces, so don't worry about that when you complete yours. Now it sits above my monitor just looking awesome

Works great, it is an awesome product for those who are looking to prototype. I can often put multiple projects on the same board with this because it's so big.

Working great for a little project I'm working on, a rear view night vision camera and display for my bike. I'm using this with a raspberry pi and this awesome little monitor that is powered by the HDMI cable from the raspi: https://www.amazon.com/gp/product/B01LXGRHK0/ref=msg_ctr_lk_pdt

I've used it for only one simple project so far, but it's pretty handy.  I'm taking off 1 star from the rating because one time it took me 15 minutes to pull out one of the pegs from the board whereas the other ones went in and out with a little force.  They are kept in place purely by friction.  Assembly was fairly straight forward, and I like that it folds up and stands vertically.

Great board. Can't beat it for the price.
I installed the driver located here:

I'm on Windows 8 and it worked without any problems. I just selected the Arduino Nano in the Arduino IDE and it works.
I've also downloaded a program to it via the ICSP header using a USBTInyISP and that works fine as well.

The breadboard has an ample number of connection points for most projects.  I do wish, however, that someone would manufacture an affordable breadboard with an attached AC/DC power supply.  This breadboard requires an external power supply.

i bought these boards to solder together a small resistance board for a passlock II bypass, i just wanted something cheap to hold the pot and resistors and keep the wires nice and managed. i have to say though, these are nice little boards, tinned on both sides of the board and pretty tough. my only minor complaint is the holes are a hair on the small side but for the price, there worth keeping a few around for a rainy day.

I purchased this micro controller to build a macro keyboard to help me with repetitive tasks. When I got the package it was sent in an Amazon padded mailer and the cardboard box inside was partially crushed. I carefully inspected the board and it appeared in good condition and so I connected it to my computer and successfully flashed on a test program. Thats when I discovered the board has a short and was sending keyboard inputs to my computer with no buttons or cables connected to the board. If I touched a pin with anything metallic that pin would start repeating itself or switching between pins.

I requested a refund and will send this board back and have already ordered a new one. From what I can see this board does exactly what I want with a very nice form factor. I am giving this review four stars because Amazon did a poor job shipping the package. Otherwise this board should have been flawless.

P.S. The Arduino software found the board with no issues!

Super easy to work with. Cut a Micro-SIM into the nano Sim. Just make sure you use the metal tray to hold the MicroSIM before cutting.

When there is only 1 USB 3 port and you need more...

These were plug and play for me after choosing the Nano in the Arduino IDE. I've used them in several projects and they have worked flawlessly.
