Product detailed description
A popular development board compatible with Arduino UNO R3 – an ideal choice for beginners and advanced users alike. It offers a perfect price/performance ratio and broad hardware and software support. Thanks to the integrated USB converter, it can be easily connected to a computer, and you can immediately start programming in the Arduino IDE environment.
The board includes a USB type B connector and a standard 5.5/2.1 mm power connector. Programming is done in the Arduino Language using the well-known Arduino IDE environment. You can use either USB power or an external source (e.g. adapter or battery).
Unlike the original, this clone does not use a USB converter based on ATmega16U2, but a commonly available CH340G chip or its alternative.
CH340 Driver Warning:
- Some newer CH340 drivers have an error: although the COM port is visible in the device manager, an error occurs when uploading code to the board:
can't set com-state for "\\.\COMx". The solution is to install an older version of the driver – you can find a download link in the Related Files section. - We have seen cases on Windows 11 where even reinstalling the driver does not lead to success. Therefore, we recommend purchasing a board without a CH340 converter in this case, such as this precise clone with ATmega16U2.
