ATmega328P-PU 8-Bit AVR Microcontroller – DIP-28 Package
$8
The ATmega328P-PU is a high-performance, low-power 8-bit AVR microcontroller in a 28-pin DIP (Dual In-Line Package). It’s the same chip used in the original Arduino Uno and is ideal for custom embedded systems, DIY electronics, and educational projects.
The ATmega328P-PU is a popular AVR microcontroller featuring 32KB flash memory, 1KB EEPROM, 2KB SRAM, 23 general-purpose I/O lines, and 6-channel 10-bit ADC. Clocked at up to 20 MHz, this MCU is fully compatible with the Arduino Uno bootloader, making it a top choice for Arduino-based custom boards and standalone projects.
Its DIP-28 package allows for easy prototyping on breadboards and veroboards, and it can be programmed via ISP or bootloader using the Arduino IDE.
