Atmega328P Microcontroller Replacement for Arduino Board

Difficulty

Easy

Steps

Time Required

5 - 10 minutes

Introduction

This is a guide on how to replace a ATMega328P microcontroller (Code: X000048) on an Arduino UNO R3 Board (Model: EL-CB-001, Code: A000066). This guide does not require any specialized skills or knowledge.

The ATMega328P processes the instructions in C from the Arduino IDE. If damaged, the code cannot be executed. Fortunately, replacing the microcontroller is a simple and uncomplicated process. Before starting the repair, please unplug the the Arduino board from the USB.

Tools

Spudger

Parts

ATMega328

Step 1

Place the Arduino UNO R3 board on a flat clean surface.

Step 2

On the right side of board, position a nylon spudger in between the microcontroller and the dip socket, and gently lift upwards to pry it out.
The bottom of the microcontroller can be scratched if not done carefully. Do not use a metal tool for this step.

Step 3

Repeat the same process on the other side.
Lift both sides evenly to prevent any damage to the pins.

Step 4

Repeat steps 2 and 3 until the microcontroller is loose enough to remove out of the socket.

Step 5

Remove replacement microcontroller out of packaging.

Step 6

If needed, straighten the pins of the replacement microcontroller and place it directly over the dip socket.
Make sure the notch on the side of the microcontroller is facing the right, matching the white lines on the board.
