The Arduino Pro Mini 3.3V 16MHz is a compact and versatile microcontroller board based on the ATmega328P. It is designed for projects requiring low power consumption and operates at 3.3V with a clock frequency of 16MHz. The board is similar to the Arduino Uno but lacks a built-in USB-to-serial adapter, making it smaller in size and suitable for applications where space is limited. It retains compatibility with the Arduino IDE, allowing easy programming and deployment of projects in various fields such as robotics, sensors, and battery-operated devices.
