Improved Arduino Nano

This is an improved version of Nano, only with ESP mic and screen. This is good for older design projects that require too much in a small space.

Pros
  • A Dream Come True
Cons
  • Functionality

Some non-standard issues, but that's okay.

The product I received had a curved OLED screen but for a breadboard this would be acceptable. There was no pin sticker in the product description. The default program loaded on the ESP32 didn't work and I thought the product was buggy. I did not attempt to change the program in case I had to work with support to fix the problem and justify a return versus mine or someone else's program. The program should find Wi-Fi networks and display their names. The default program reported finding "-2…

Pros
  • Complete set
Cons
  • Style 90

Overall great but good for single board computers

Brand new and I screwed up. Although the MCU still works as it should, my MCU doesn't have a bonus meter. Be extra careful when cleaning the board with alcohol after soldering connectors. This will ruin the OLED. Lesson learned.

Pros
  • Best
Cons
  • Anything I can add

Worked great for single board computers

I wrote an ESP32 Bluetooth application on a normal development board with external OLED and then bought this board because I wanted something cleaner as a final product. All I needed to do in my opinion to get my code working perfectly was use a different output/configuration for OLED that is documented in other reviews. I would give it 5 stars but the only thing missing is a way to mount it. I wish more of these boards had mounting holes.

Pros
  • Quality construction
Cons
  • Not everything fits

Failed first time. Make sure GPIO12 is not low on boot

The first one I ordered worked when I turned it on using the USB cable connected to my laptop. But 10 minutes later he was dead. I didn't solder anything. It just didn't work anymore. I have a backup There were problems with the exchange until I found that you can't use GPIO12 or won't boot.

Pros
  • Handsfree
Cons
  • Infinitely sluggish

Great overall but best in the Computers & Accessories category

Brand new and I broke it. Although the MCU still works as it should, my MCU doesn't have a bonus meter. Be extra careful when cleaning the board with alcohol after soldering connectors. This will ruin the OLED. Lesson learned.

Pros
  • Computer Components
Cons
  • Long delivery time
