Atmega328p-Au SMD Microcontroller Ic – 8-Bit Avr TQFP-32.

The ATmega328P-AU is a high-performance 8-bit AVR microcontroller designed for compact and professional PCB designs. It offers the same core functionality as the ATmega328P-PU DIP version but comes in a smaller TQFP-32 surface-mount package, making it ideal for custom PCB manufacturing and space-saving applications. This microcontroller is commonly used on Arduino Nano, Arduino Pro Mini, and many custom embedded boards. It is based on the AVR RISC architecture and provides fast processing, low power consumption, and excellent reliability for a wide variety of electronics projects.
