Arduino Nano R3, ATmega328 Clone, Unsoldered pins

Product detailed description

Arduino Nano format development board. Its dimensions and pin layout make it an excellent module for various electronic designs.

Thanks to the integrated USB connector and USB converter, you can record the program to the board without any special wiring. On the software side, the board is programmed via the integrated development environment Arduino IDE, which offers a simple and clear WIRING programming language.

This board is suitable for both beginners and advanced students and its versatility makes it suitable for almost any project.

ATTENTION! We are starting to encounter an error with the latest driver of the CH340 converter manufacturer, when the driver is installed, the COM port is also visible in the device manager, but when trying to upload the software to the board, the upload ends with an error "can't set com-state for "\\.\COMx". The solution is to reinstall the current driver with an older version. We have added the functional version for download in the Related Files section.

We have also encountered an issue where reinstalling an older driver does not work, this is an issue in conjunction with Windows 11. Unfortunately, there is no solution at present.
