Introduction: How to Fix Fried Arduino Nano/Uno/Mega
While I was working on a project which includes an arduino I accidentally shorted it and now its dead. But it can be fixed really easily, So lets get started !
In this post I am fixing the Arduino nano if you have fried Uno or mega skip to step 7, but do read all steps once.
Step 1: Watch the Video
If you get bored of reading stuff you can watch my videos on YouTube ! Click Here
Step 2: Analyzing the Problem !
There are two ways in which you can burn your arduino
2) External Vin pin
Step 3: USB
If you were using USB to power your arduino when it died if you flip it around you will see a black component, which is a diode and if u look closely it has a small bulge area or a spot swelled indicating it is dead which is the case for me so replacing it will fix the arduino, but before fixing it lets look at the other way you might have shorted it.
Step 4: Vin Pin
If you were using Vin pin when it died then if you flip it around you will see a small bulge area on this which is a voltage regulator replacing this will fix your issue, but in my case it works via Vin pin but not USB so I need to replace the diode so let's do it
Step 5: Components & Tools!
1) Soldering Iron
2)SMD MBR0520Tp Schottky Diode
Step 6: Soldering !
I don't have SMD Schottky Diode at the movement so I will be using general purpose short key diode.
And its time for the Soldering
I have turned the legs of diode for my convenience.
and Its done !
Step 7: For Uno and Mega
Similarly if you have shorted your Arduino Uno or Mega, You need to replace 500mA Fuse(Shown in pic 2) or Voltage regulator(Shown in pic 3) which is same as nano
It will fix the issue !
Step 8: Thank You !
