ATmega328 Boards

Introduction:

The ATMEGA328PB is a high-performance, low-power microcontroller from Microchip Technology and the latest iteration of the venerated ATmega328 chip series. It is based on the AVR enhanced RISC architecture. The ATMEGA328PB is popular among makers due to its versatility, affordability, and the wide range of applications it can be used for; it is the core processor underlying many popular board.

Platforms:

Arduino Uno

The Arduino Uno is the most popular board based on the ATMEGA328PB. It is an open-source platform used for building electronics projects. The Uno board has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, and a power jack.

Arduino Nano

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328PB. It has similar functionalities to the Arduino Uno but in a smaller form factor, making it suitable for projects where space is a concern.

Pro Mini:

The Pro Mini is a compact version of the Arduino Uno compatible board. It is designed for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.

Programming the ATMEGA328PB:

The ATMEGA328PB can be programmed using the Arduino IDE, a user-friendly interface that allows you to write code and upload it to your board. It supports C and C++ languages. The Arduino IDE comes with a library of pre-written code, called "Sketches", which can be used to simplify your programming tasks.
