The Atmega328P is at the center of every Arduino Uno board and acts as the 8-bit microcontroller that controls and interacts with sensors, motors, relays, and other electronic devices. The ATmega328P-U shown here is a dual in-line package microchip that can be placed on a breadboard, making it ideal for projects that require enclosure, or prototypes moving beyond the development board phase. The ATmega328P-U is also a great selection for Internet of Things (IoT) development, as its inherent power consumption is very low without LEDs or regulators.

Included in the ATmega328P-U Package:

• 1x ATmega328P-U with Arduino Bootloader
