Summary of Wing Tip Extensions for Arduino
The article describes the creation of a custom 45-degree extension PCB, named "Wing Tip Extension," designed to work with the Arduino UNO R3. Motivated by the high cost of commercial extension boards, the author uses the project to learn Eagle PCB layout software. The process involves designing the PCB layout, printing it onto a transparency sheet, exposing a pre-sensitized board to light, etching it, and then cutting the board to size using standard PCB fabrication techniques.
Parts used in the Wing Tip Extension:
- Arduino UNO R3 board (compatibility target)
- Pre-sensitized PCB board
- Transparency sheets
- Laser printer
- Fluorescent lamp (for exposure)
- Etching chemicals (not specified)
- PCB cutting tools
Greetings,
One late night of web surfing I came across some 45 Degree Extension boards.
Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H.
“Yikes!”
I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing Tip Extension” was born!
Step 1: Layout
PCB Layout, I’m sure this took longer than it should have but I did learn a lot building this simple board.
I designed this to work with the Ardunio UNO R3 board so that’s why there are extra pads than normal.

Printed the layout on transparency sheets with my laser printer.
Used a Pre-sensitized Board, and 10 min exposure with a fluorescent lamp.
Standard etching technique were used.
Step 3: Cut
Cut the boards to size
