You can connect a 6 to 20V external power supply here, but the recommended voltage and current ratings are 7 to 12V and 1A only. The Arduino Nano and Uno are equipped with very similar processors ...

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like ...

unlike the 5 volts used by the Arduino UNO, it maintains compatibility with 37 pins, including a 22-pin HSTX FPC port for DVI video output, a STEMMA-QT interface, and a 3-pin JST-SH port for debugging ...
