Microcontroller:
Powered by the ATmega328P or ATmega168 microcontroller.
Runs at a clock speed of 16 MHz, offering solid processing capabilities for a variety of projects.
Digital and Analog I/O Pins:
Offers 14 digital input/output pins, 6 of which support PWM (Pulse Width Modulation) for controlling devices like LEDs, motors, or servos.
Includes 8 analog input pins with 10-bit resolution, suitable for reading sensors and interfacing with analog devices.
Compatible with breadboards for easy prototyping.
Compact Form Factor:
Measures just 45mm x 18mm, making it perfect for projects where space is limited.
The small size is ideal for wearable technology, embedded projects, and DIY gadgets where the standard-sized Arduino boards are too large.
Power Supply:
Can be powered via USB Mini-B cable or an external power source (7-12V) through the VIN pin.
Includes a 5V voltage regulator, providing regulated 5V to the board and peripherals.
Features a reset button for restarting the program.
USB Communication:
Uses a USB Mini-B port for uploading code and communicating with a computer.
The FTDI FT232 or CH340 chip (depending on the version) serves as a USB-to-serial converter for reliable data transmission and programming.
Memory:
32KB of flash memory for program storage, with 2KB of SRAM for variable storage and 1KB of EEPROM for non-volatile data storage (ATmega328P version).
Lower memory capacities on the ATmega168 version (16KB flash memory).
Programming:
Programmed using the Arduino IDE, a simple and easy-to-use development environment that supports C/C++ programming.
Compatible with PlatformIO and other development tools for advanced programming and debugging.
Extensive libraries available for interfacing with sensors, displays, motors, and other peripherals.
Onboard LEDs:
Includes an onboard LED connected to pin 13, useful for testing, debugging, and simple feedback applications.
Breadboard Compatibility:
Designed to fit directly into standard breadboards, making it ideal for prototyping and testing circuits without soldering.
Open-Source Design:
Fully open-source, with schematics and design files available for modification and customization.
Wide community support and a large number of compatible libraries, shields, and accessories.
