Arduino Uno R3 (SMD) with cable

The Arduino Uno R3 SMD is a popular and versatile microcontroller board based on the ATmega328P microcontroller. The SMD (Surface-Mount Device) version features the ATmega328P microcontroller in an SMD package, offering the same functionality as the traditional UNO R3 but with a more compact design. It is widely used for a variety of projects, from simple experiments to complex prototypes.
