Arduino Uno Boards

Arduino Uno Boards are based on the ATmega328P chip, designed for simplicity, ease of use, and versatility in various electronic projects. As part of the open-source Arduino platform, the boards are equipped with 14 digital input/output pins, six analog inputs, a USB connection for programming, and a power jack for an external power supply. The Arduino Uno Boards operate at a clock speed of 16MHz, making it suitable for handling various sensors, motors, LEDs, and communication modules. The Arduino Uno supports digital and analog interfacing, enabling applications ranging from basic LED blinking to complex robotics and Internet of Things (IoT) systems. Its simplicity and broad community support make it a favored choice among hobbyists, educators, and professionals for prototyping and developing embedded systems, interactive devices, automation solutions, and more.

Features

ATmega328P microcontroller, 8MHz to 120MHz clock speed range (depending on model)
