I had to buy one of these for a college class, and spend hours on an assignment wondering why my program wouldn't run properly and after comparing with classmate, we tried every part and it was definitely the arduino board that was the issue. Waste of money and time, do not buy Read more

I never write reviews but saw many on here that had issues. Keep in mind the chip is not a 328p like the normal uno uses. It is a 328pb. The pb variant actually has upgraded features but is backwards compatible. First thing is to make sure you go in arduino ide and go to settings. At the bottom there is a button that you can add a web address. There will be a link somewhere near there that will bring you to a page that lists many boards etc. Find minicore and copy paste the link into the arduino input box. Hit ok and then go to your board manager and find minicore. Hit install. Once installed. Go to where you select your board type and you should see a listing of minicore. Next menu pick the atmega328. Here's the part not to forget in your menus you will have a bunch of added options. Find the one that says "variant" and select "PB" now you should be able to upload sketches to it (may need to install 340G drivers. I don't know as I program my boards with a usbasp type programmer).

I use these for so many things. Right now I am building an opener for my Observatory roof that is controlled by an arduino uno and a relay board. Read more

I now have 2 of these and am enjoying using them. Have not had a problem with it and have had it some time now. Read more

After installing Win 11 drivers, I was able to load several sketches however each time loading became slower and slower until it would no longer accept a sketch. I assumed the boot loader was somehow damaged. When I tried to burn the boot loader using an Arduino as an ISP or a USBTiny ISP, I encountered one problem after another. While I was eventually able to burn the Uno boot loader, it does not work. The problem is that my unit has a Atmel 328PB not a 328P and therefore it is not a Uno “compatible” board. I will be returning the board. Read more

I love these. You cannot see the UNO I bought cause I put these LCD shields on them. They went together perfectly, coded easily, and the Unos work flawlessly. (LCD 1602 shields are not included) great value for money. Read more
