How to Repair an Aruino Nano


Step 1: Purchase a new Atmega. This is the version of the chip from digikey  Atmega328P

Step 2: Carefully desolder the old processor.  I found that is very easy to lift the pads in this process.  If I were to try it again I’d probably try using a heat-gun.

Step 3: Solder the new proccessor onto the board.  Pretty straight forward, assuming the board was not damaged.

Step 4: Program the Arduino bootloader. This can be done using another Arduino board, or a dedicated programmer. I used my USBTinyISP for the first time and it works great. It interfaces directly with the Arduino IDE and is a lot more convenient than having to wire up a spare Arduino every time.

Step 5: You’re arduino is now repaired.

Bright Light Controller Board Layout

I’ve completed the layout of my previously designed schematic.  I’ve over-sized the board by a good bit so I can get a feel for the component sizes and the ease of soldering them to the board.  Below is a 3D Rendering of what the completed board should look like.
