Arduino Pro Mini

The Arduino Pro Mini is a compact and low-power microcontroller development board built around the ATmega328P (or ATmega168 in some versions). Designed for embedded and space-constrained projects, it delivers the core functionality of an Arduino in a small, breadboard-friendly form factor. Without an onboard USB interface, it requires an external USB-to-serial adapter for programming, making it ideal for permanent installations and battery-powered applications where size and power efficiency are crucial.

Available in 3.3 V (8 MHz) and 5 V (16 MHz) versions, the board provides 14 digital I/O pins—6 with PWM support—and 8 analog inputs, allowing for versatile interfacing with sensors, actuators, and modules. It includes 32 KB of Flash memory, 2 KB of SRAM, and 1 KB of EEPROM for program and data storage. Its low-power design ensures minimal energy consumption, making it perfect for portable devices and long-term projects.

Fully compatible with the Arduino IDE, the Pro Mini allows easy integration into existing Arduino-based workflows while providing a compact, efficient solution for embedded electronics, IoT devices, robotics, and DIY projects.
