ATmega328P-PU Microcontroller – 8-bit AVR, PDIP-28 Package (Without Bootloader)

The ATmega328P-PU is a high-performance, low-power 8-bit AVR microcontroller widely used in embedded systems, IoT devices, robotics, and educational platforms. Known for its role as the core component of the Arduino Uno, this version comes in a PDIP-28 (Plastic Dual In-Line Package) form, ideal for breadboarding, socketing, or through-hole PCB soldering.

Featuring 32KB of Flash memory, 2KB SRAM, 1KB EEPROM, and a variety of built-in peripherals, it offers a robust platform for both hobbyists and professional developers.

Note: This version does not include the Arduino bootloader and requires an external programmer (such as USBasp, AVRISP, or Arduino as ISP) for programming.

Key Features

• Standard AVR Microcontroller: Compatible with Atmel Studio, Arduino (with bootloader), PlatformIO

• Versatile I/O: Supports ADC, PWM, UART, SPI, and I²C interfaces
