Overview

The ATMEGA328PB-XMINI is a compact evaluation board designed for the ATmega328PB 8-bit AVR microcontroller. It features an integrated on-board debugger for seamless programming and debugging through Microchip Studio or MPLAB X without external hardware. This 'Xplained Mini' board provides full access to the MCU's I/O pins, including the enhanced capabilities of the PB variant such as the Peripheral Touch Controller (PTC).

Why Choose This Part

This board bridges the gap between raw ICs and consumer dev boards by providing an on-board debugger (mEDBG) and auto-ID support in Microchip's IDEs. The ATmega328PB itself improves upon the classic 'P' variant by offering additional timers, serial interfaces, and functional safety (FuSa) features in a familiar architecture.

Applications

Capacitive Touch Interfaces

Leveraging the built-in Peripheral Touch Controller for buttons, sliders, and wheels in consumer devices.

Low-Power Sensor Nodes

Utilizing picoPower technology and various sleep modes (down to 0.2uA shutdown) for battery-operated remote monitoring.

Educational and DIY Prototyping

Serving as a hardware-compatible alternative to the Arduino Uno for learning AVR assembly and C programming.
