The Arduino Pro Mini (ATmega328P-AU) is a compact, professional-grade microcontroller board ideal for embedded and space-constrained applications. Designed for advanced users, it offers the full power of the ATmega328P in a smaller, breadboard-friendly package.
It operates at 5V 16MHz (or 3.3V 8MHz versions) and can be programmed using an external USB-to-Serial adapter (FTDI or CH340). The board provides multiple I/O pins, PWM outputs, and analog inputs—perfect for projects like wearables, robotics, IoT systems, and custom electronics.
