Introduction: ATMEGA328 Bootloader Programming Shield for Arduino Uno

ATMEGA328P boot-loader programming shield for Arduino Uno

Sometimes it happens and you damage your Arduino Uno Atmega328P microprocessor. You can change processor. But first it need to program boot-loader in it. So this tutorial how to make this board which upload bootloader.

If you don't want to make this board, look at this tutorial >>

To build this programmer you will need >>>

1 x Atmega328P or Atmega328 PU microprocessor

2x 16MHz HC49S crystal quartz

2x 22pF 0805 ceramic capacitors

1x10K 0805 resistor

1x OR 1206 rezistor

1x 28 pin DIP socket

1x 40pins header pins

1x 75mm-75mm copper board

Step 1: PCB Board

Design printed circuit board (PCB), I was used ,,Sprint-Layout" software. Exported Gerber files.

Step 2: Soldering Board

28 DIP socket pins need to bend. I didn't want to drill holes.

After soldering this board it looks like this

Step 3: Programming Atmega328P Bootloader

1) Open Arduino software

2) File> Examples > ArduinoISP

3) Tools > Programmer > Arduino as ISP

4) Sketch > Upload

5) Tools > Burn Bootloader
