Are all #Arduino #Nano built the same?
Well it terns out not so, some of the latest (post 2021) batches of clone boards are coming sipped with the 8bit #atmega328pb as apposed the normal #atmega328p and its the extra 'b' thats makes all the difference!
In this video we'll look at how to get this new 'pb' variant working with the stock Arduino IDE so you can upload code as you would on a standard clone Nano.

This saves my day, thanks! I ordered from Mouser wrong chip: Atmega328pb and having problem uploading anything to ICT tracker (for tracking high altitude balloons). Now, I will try to do it again with method you described.

I've had permission issues with Arduino boards and Linux, a simple chmod tends to solve it.

It was a Very useful video. Very less people noticed that Arduino UNO and Nano Clone board are available in market using ATmega 328 PB chip-set. This board after programming using ARduino UNO board Selection, it Upload codes. Some Time it Works Properly and Maximum time it works abruptly, Freezes, Restart and many issues. I am a Hobbyist and Academic Project developer and I have many Arduino UNO Board with Atmega328 PB Chipset. Finding for the Solution for this clone board and your this video was helpful for me. Thanks a Lot.

The most frustrating thing is that these 328PB products are still sold as and even labeled as 328P as you mention. I have two boards with these two chips, I plugged them in both not working, tried a lot of stuff and finally I discovered that 328PB exists... 😂🤣 After that I found your video. Thanks and subscribed, nice job.

Thanks for this. It was driving me crazy! I ordered 328P and that's what the listing said, but received 328PB and ran into problems as you can imagine. 6 hours later I zoomed in on the chip to see the faint 328PB stamped and not 328P.

Glad I could help! Totally understand the frustration! Hence this video to help out fellow makers. Hope you've all sorted now?

Glad to hear that... I knew when i went though this issue I had to make this video as it would be helpful to so many people!

I have the same problem with the Chinese Ardunio NANO that comes with the MEGA328PU - TH chip. I can't write the bootloader to it, in the IDE this message comes: avrdude: Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check. Does anyone know how to use -F to override this check or solve this problem?

Got this 328PB Version and after trying many things i discovered ... you can use the standard Nano Settings - BUT you must use ATmega328P (Old bootloader) as the Programmer and everything is ok 🙂

Oh how interesting... is that a fact? Well thanks for the info!

@bobbycount1503 6 ай бұрын

It's a fact. Using it for a few days now - behaves quite as you would expect from a Nano. Just a little anoying to swich from regular to old Bootloader (using both versions) 🙂 @@WiFiSheep

Just for the record maybe someone will find it useful. Some Pro-Mini 3.3v with 328PB they refused to upload code from Serial/FTDI no matter if the bootloader is OK. Try to upload the sketches via programmer, maybe it will work.

Thanks for the video, you saved three Arduinos from going to trash :)

I tried to find the library and it is gone.😢

@WiFiSheep 10 ай бұрын

I have just tested the links and library again on a fresh IDE install on another machine and have had no issue... So im not sure what the issue is here?

@R.-. Жыл бұрын

Did you have to figure all this out yourself? It strikes me as strange that anyone could make a product this incompatible with no instructions about how to use it.

@WiFiSheep Жыл бұрын

I cant take credit for everything, and trust me I did a lot of hours of trying to figure this out. I honestly didn't even know 328pb was a thing until this happened. And the products are still sold as and even labelled as 328p. So theres no additional documentation at all! But as ive figured this out, it was important to share with the community, as so many are going to hit this issue going forward.

I've done everything I can think of with an Arduino Uno with 328PB but no luck any tips?

@WiFiSheep Жыл бұрын

If its an Uno are you sure its a 238PB? and not a 238PU?

@mechanichell Жыл бұрын

@@WiFiSheep Yeah I looked at it from close up it's a 328PB, looks like the bootloader is successfully installed but I cannot for the life of me upload any code to it.

@WiFiSheep Жыл бұрын

Make sure your on the correct COMs port for the device, that the 328PB library is installed and running as shown in the video... Make sure you have the CH340 drivers installed if your on PC or MAC sparks.gogo.co.nz/ch340.html If still issues You might want to try refreshing the boot loader. Just to be sure... you're not trying to use external HEX uploads like Xloader? As these dont work with 328PBs

@mechanichell Жыл бұрын

@@WiFiSheep checked the port, have the library installed, have the drivers intaller, have a fresh bootloader installed, no external uploads either.

Thats an interesting one! I assume you can use other Arduino ok and the IDE is working? Might be permissions issues, if the IDE is getting blocked... failing that chip or board issue ... might be work hopping on the Arduino Forums
