Arduino Promini - ATmega328 - 8MHz

 It operates at 5V and runs at a clock frequency of 8MHz, making it suitable for low-power applications.

The board is equipped with the ATmega328P microcontroller, featuring 32KB of flash memory, 2KB of SRAM, and 1KB of EEPROM. This microcontroller provides sufficient resources to handle a wide range of tasks and execute Arduino sketches.

With its compact size, the Arduino Pro Mini is often used in applications where space is limited, such as wearable electronics, remote-controlled devices, and sensor nodes. It can be easily integrated into custom circuit boards or connected to external components through its through-hole pins.

The board operates at 5V, allowing compatibility with a wide range of sensors, actuators, and other electronic components. It can be powered using a regulated 5V power supply or a USB-to-serial converter module.

Programming the Arduino Pro Mini is straightforward, as it supports the Arduino IDE and uses the same ATmega328P bootloader as the Arduino Uno. This enables users to easily upload their sketches using a standard USB-to-serial adapter.

The Arduino Pro Mini - ATmega328 (5V) 8MHz offers a minimalistic design without the USB interface and onboard voltage regulator found in other Arduino boards. This makes it more suitable for embedding into projects where a smaller footprint and lower power consumption are desired.
