Arduino Pro Mini ATmega328P 5V 16MHz Development Board

The Arduino Pro Mini ATmega328P 5V 16MHz is a compact microcontroller development board designed for embedded systems, electronics prototyping, and projects where space-efficient hardware is essential. Powered by the ATmega328P 8-bit AVR microcontroller, it provides a familiar Arduino-compatible programming environment in a small form factor suitable for permanent installation in custom devices.

Operating at 5V with a 16MHz clock frequency, the board offers 14 digital input/output pins, including 6 PWM-capable pins, and 8 analog input channels on compatible board versions. It also supports serial communication, SPI, and I²C, allowing it to interface with a wide range of sensors, displays, communication modules, and other electronic components.

The Pro Mini includes 32KB of Flash memory, 2KB of SRAM, and 1KB of EEPROM for program storage, runtime data, and persistent settings. Its compact PCB and available header connections make it suitable for custom circuit boards, robotics, automation prototypes, sensor networks, and battery-powered embedded applications where its 5V operating requirements are appropriate.

Unlike the Arduino Uno, the Pro Mini does not include an onboard USB-to-serial converter. Programming therefore requires a compatible USB-to-TTL serial adapter, typically connected through the six-pin serial programming header. The board can be powered through its regulated VCC input or through the RAW input within the limits of the specific board version.
