The Brain of Your Next Arduino Project

Power your custom electronics projects with the ATMEGA328P-PU, the versatile and popular microcontroller found in the Arduino Uno. Whether you're building a "barebones" Arduino on a breadboard, designing a custom PCB, or replacing a chip in an existing board, this is the component you need.

Its standard 28-pin PDIP (Dual In-line Package) format makes it perfect for hobbyists, students, and professionals alike, as it fits directly into breadboards and standard IC sockets.

Key Features:

• Arduino Compatible: Fully compatible with the Arduino IDE. Program it just like an Arduino Uno or Nano using your existing sketches.
• PicoPower Technology: The "P" signifies Atmel's PicoPower technology, ensuring low power consumption ideal for battery-operated and energy-efficient projects.
• Versatile Package: The user-friendly DIP-28 package is perfect for prototyping on breadboards and soldering onto through-hole PCBs.
• Powerful Core: 8-bit AVR RISC-based microcontroller with 32KB of flash memory (for your code), 2KB SRAM (for variables), and 1KB EEPROM (for non-volatile data storage).
• Rich Peripherals: Features 23 programmable I/O lines, a 6-channel 10-bit ADC (Analog-to-Digital Converter), hardware timers, and SPI, I2C, and UART communication interfaces.

Pro-Tip: Pair it with our 28-pin DIP socket (as shown in the images) to easily insert and remove the chip from your circuit board without soldering.
