ATmega328P Microcontroller Board Products

Description

The ATmega328P is the most popular microcontroller that made its appearance in the Arduino Uno R3 board, with the advantage of having a large amount of documentation, guides, and tutorials available.

The processor consists of an 8-bit 16MHz AVRAVR microcontrollers derives its name from its developers and stands for, Alf-Egil Bogen and Vegard Wollan RISC microcontroller, and is also known as Advanced Virtual RISC. ATmega (max speed 20MHz) with Advanced RISCReduced Instruction Set Computer architecture. The memory is limited to only 2048 bytes of SRAMStatic Random Access Memory, 1KB of EEPROMElectrically Erasable Programmable Read-Only Memory, and 32KB of flash memory (of which 0.5KB is used by the bootloader).

The "328p" in the ATmega328P chip name has 32 for 32KB of flash memory, 8 for 8-bit architecture (data bus), and p for "pico-power" (i.e., consumes less power under certain circumstances). This means that the ATmega328P should be used for less intensive processing applications that do not consume much memory.

There are many ATmega328P microcontroller boards available that come in different sizes, layouts, and connectors.

Prototyping boards, such as the Arduino Uno R3 and compatible boards, have a larger layout that is convenient to interface with when plugging in power and I/OInput/Output.

Small footprint boards, such as the Arduino Nano, SparkFun Pro Mini, Adafruit Metro Mini and Pro Trinket, are less expensive, consume less power, and can be embedded in your application.
