Arduino Pro Mini

The Arduino Pro Mini is a compact and versatile microcontroller board designed for projects where space is at a premium. Based on the ATmega328 microcontroller, the Pro Mini offers the full functionality of an Arduino board in a significantly smaller form factor, making it ideal for embedded projects, wearables, and other applications where size and weight are critical constraints.

Key Features

1. Microcontroller: The Arduino Pro Mini is powered by the ATmega328 microcontroller, which operates at a clock speed of 16 MHz (5V version) or 8 MHz (3.3V version). This provides a good balance of processing power and energy efficiency for a wide range of applications.
2. I/O Pins: The board features 14 digital input/output pins, 6 of which can be used as PWM outputs. It also has 8 analog inputs, providing ample options for interfacing with sensors, actuators, and other peripherals. The pins are laid out in a breadboard-friendly format, making it easy to integrate into prototypes.
3. Memory: The ATmega328 microcontroller on the Pro Mini includes 32KB of Flash memory for storing your program, 2KB of SRAM for runtime data, and 1KB of EEPROM for non-volatile data storage. This memory configuration is sufficient for most small to medium-sized projects.
4. Power Supply: The Pro Mini can operate at either 5V or 3.3V, depending on the version you choose. It has a raw input voltage range of 3.35V to 12V, which can be supplied through the onboard voltage regulator. This flexibility allows you to power the board with various power sources, including batteries.
5. Programming: Unlike other Arduino boards, the Pro Mini does not include a built-in USB-to-serial converter. Instead, it requires an external USB-to-serial adapter or an FTDI cable for programming. This design choice helps keep the board size small and reduces cost, but it does mean you’ll need additional hardware for programming.
6. Form Factor: Measuring just 18mm x 33mm, the Arduino Pro Mini is one of the smallest Arduino boards available. Its compact size and lightweight design make it perfect for projects where space is limited, such as wearable technology, compact robotics, and embedded systems.
