Introduction: How to Burn a Bootloader to Clone Arduino Nano 3.0
please support & share our mission;igg.me/at/smartplants
I have recently purchased an Arduino Nano 3.0 Clone which came without a bootloader. I am sure there are many other people who are in the same situation as me, and may have freaked out a little bit at first ! Don't worry, in this instructable I will show you how to easily install a bootloader to your new clone.
let's see how it's done..>
ATTENTION - some clones are different. they don't have an ftdi chip, which may cause your computer to not see the arduino once plugged in with the usb. if this is the case, please follow these steps; https://www.instructables.com/id/How-To-Burn-a-Boot... thanks to author Gegec for his help on noticing the problem and solving it as well :)
Step 1: Get a Clone
It is very easy to find a clone of any board on the internet. Or you can at worst make yourself one...
They are extremely cheap, I have seen pinless nano boards as low as $5 online. You just have to do some work on your end, which is a very fair give and take if you ask me.
I don't want to advertise any names here, if you just search the board that you want with the word clone next to it, you will find some. Mine is called Funduino Nano, which is an open source company apparently just making amazing products at real fair prices..
Look how small an arduino nano is, it's the size of my pinky finger. This will help me tremendously in my new projects, huge improvements on size!
Step 2: Test It First !
Plug it to the computer with the USB cable.
Make sure it turns on, and yes it did.! So far we are safe.
Now try to upload the blink sketch to it using the Arduino software on your computer. (file>examples>basics>blink)
You will most likely get the error in the second picture. This has nothing to do with the code being right/wrong. It just simply means that your computer and the board aren't communicating correctly, in our case the lack of the bootloader prevents us from doing so.
If your clone did work with the sketch upload, then even better.! you found one that is pre-installed. just start using it...
If you get the error message, keep on reading..>
Step 3: Simple Few Steps
Now you need to find a working arduino board, doesn't matter if it is a nano or not, I have used my "real" uno r3 and worked perfectly. If you don't already have one, try borrowing it from a friend.
If you have any grab your female - male breadboard jumpers. These will make the process even faster and easier. BUT I didn't have any so, instead of waiting 2 weeks for them to arrive online as well, I had to take some extreme measures!
First we need to locate and get familiar with the ICSP pins. On mine just one of them was marked with a number, top right as 1. Here is what they look like in the schematics. So right under 1 had to be 2 and next to one was 3 and so on...
Now that you are ready lets begin - do the following steps in order;
STEP 1 - Upload ISP
-Connect the working arduino to your computer.
- Open the arduino software on the computer
- Go to Tools>Serial Port>COM (and make sure that the correct COM port is chosen - ask me if you don't what this means)
- Go to Tools>Board>Arduino Uno (in my case uno, this is the arduino that is already working not yet the other one)
- Go to File>Examples>Arduino ISP (a new sketch screen will open with the ISP code written in it)
- Verify then Upload (your board will start blinking for a bit, it means it is loading, wait until done uploading)
- Unplug the arduino. Now it has the ISP code in it, all we have left to do is connect them together and run a few commands again...
STEP 2 - Connect 2 arduinos together
- Now connect the two arduinos together, to do this without female-male jumper cables was time consuming, you have to be VERY CAREFUL and take your time bending the wires, other wise you may short your circuits. ask me first ! In the second picture you can see that first I put the ICSP pins through a piece of paper and then carefully wrapped around them the corresponding wires. Make sure they grab on very tightly, use a small flat head screw driver to bend them. Take your time, don't be rough.
- Connect them this way;
pin 1 on clone to D12 on working arduino
pin 2 on clone to 5V on working arduino
pin 3 on clone to D13 on working arduino
pin 4 on clone to D11 on working arduino
pin 5 on clone to D10 on working arduino
pin 6 on clone to GND on working arduino
STEP 3 - Burn Bootloader
- Keeping all the wires intact and unmoved in step 2, connect the working arduino back to the computer with the USB
- Go to Tools>Serial Port>COM (and make sure again that the correct COM port is chosen - ask me if you don't what this means)
- Go to Tools>Board>Arduino Nano w/Atmega 328 (this time we choose the non working arduino, in my case nano atmega 328)
- Go to Tools>Programmer>Arduino as ISP
- Go to Tools>Burn Bootloader (this is it, after the LEDs stop flashing your board is ready to use !!!)
Do all of the above steps in ORDER !!! no skipping steps
Always make sure that the correct COMM port and correct board are chosen before uploading a sketch to avoid errors...

Please be positive and constructive.
I tried to restore the bootloader at my Arduino Nano. It was working before but suddenly i can't compile a programm anymore. During compiling proces it hangs..
So i guess something is wrong
I used your procedure but get errors : Its partly in Dutch.. :-)
Arduino: 1.8.5 (Windows 10), Board:"Arduino Nano, ATmega328P"
avrdude: Expected signature for ATmega328P is 1E 95 0F
Double check chip, or use -F to override this check.
Fout bij het branden van de bootloader.

Is my Arduino Nano "gone" ??
