#12 Repairing broken Arduino Nano Clones, Episode 2 - Power

In this video, I'm showing how to troubleshoot and repair a broken Arduino Nano clone. I have two devices that appear to be faulty with some kind of power issue, and I manage to fix both.

thank you for this! i'm a newbie to arduinos and my nano clone mysteriously broke the other day and i couldn't make sense of all the arduino charts i was seeing online, but you explained it perfectly. thank you for mentioning that mixing up the GND and 5V would fry the diode because that was exactly my mistake LOL

[deividribeiro]

Thank you very much. My module was a little bit different, and the diode I needed to replace next to the regulator LM1117, in my board was just one diode. You can just take off your diode and put a jumper in the same place, but never connect your arduino in voltages upper than 5V when connected in your PC.This diode is a protection, he never let the voltage upper 5V back to the usb cable and burn your usb port.

greetings from Brazil.

I had the same problem! And for some reason my diode burned out!
Your video helped me a lot!
I used a DC DC Boost converter and set it to 5 Volts. I connected it to the 5V pin and GND!
And my board worked!
2 of my boards had the same problem!
And 1 had undervoltage!

Good information, I would have never expected that it would ever be worth it to fix these but here we are lol

love this video helped me with my clones!!!

I worked on so many crappy boards that "snipping it out" gave me nightmares of pads lifting off the board. Scary stuff.

Thank you very much for the explanatory repair video. Do you mind adding the datasheet link and the name of the diode under the description of the video? Best regards.

Excellent repair, on Nano troubleshooting. Thanks.
I noticed that on both repaired Nanos, the power LED was still not illuminating-must have also been blown? Did subsequent usage present any further issues? I ask as, an electronics' newbie, I inadvertently powered up my Nano, from a 3S Li-ion battery, during testing, of a 7805 regulating circuit (to prevent such from occurring: knocking head on table), I built; must have had twin power leads connected. Thought it would have been the AMS1117 blown. You have pointed me the right direction. Thanks.
Finally, as I've never worked on SMD components, what temperature do you set your soldering iron to, for these delicate repairs? thanks.
I am subscribing, & will look at more of your vids, as I like your style,

Handy Info, I have a fwe of these 'broken' around, and these days, they are worth fixing, as you said.
Any details on the diode you used or ordered?

[pierpa_pierpaolo]

What kind of problems have you had with the Arduino Nano? I saw that you changed the sdm rectifier diode!!! Then did you solve it? in my case the board is detected but it does not configure!!! Which "COM" port do you use? Thank you very much.

Hi, this is really a good video. Please mention the name of the diode. Thanks in advance

[Handlebrake]

Is it off that my usb to serial converter under 5he board doesn't say anything? I have one nano that states ch340, or whatever it is, but the other three are blank.

Could I use a rectifying diode instead of these SMD ones? Thanks

arduino nano code not uploading bro in board problem

My Arduino nano is not showing up in my pc and RX, TX, and PWR leds get's on when plug it in my pc but it shows unknown device what should I do

Sir my Arduino nano ic heated during make water level LCD not show text
