Description
The Arduino Uno SMD is a compact and reliable microcontroller board based on the ATmega328P (SMD version). It functions similarly to the standard Arduino Uno, but features a surface-mounted (SMD) ATmega328P chip instead of the traditional DIP package. This makes the board slimmer and slightly more difficult to replace the microcontroller if needed.
