HOW TO ADD A LOW PROFILE WIFI BOARD TO A RASPBERRY PI ZERO
--

[UPDATE] It's probably best to use the 5v and Ground GPIO pins instead of the testpads, so use that if you have the option.

This guide will show you how to attach a low profile wifi board to a Raspberry Pi Zero. It uses the test pads underneath the board to save tonnes of space, and might work well in embedded hardware projects.

Make sure that you have the wifi configured on the operating system before you attach the wifi board.

PARTS

- Raspberry Pi Zero
- Wifi dongle (make sure it's compatible with the Pi)
- Thin wires (you can salvage them from an old USB cable)
- Electrical tape

TOOLS

- Soldering iron
- Helping Hands
- Wire cutters/strippers

HOW-TO GUIDE

Step 1. Remove the wifi board from inside the dongle casing. I added some solder to the contacts.

Step 2. Cut and tin the red, white, green and black wires. Make them about 40mm long.

Step 3. Solder the wires onto the wifi board and the pads under the Pi Zero using the pinout diagram from earlier in the video.

Step 4. Cover the wifi board with tape, fold it over and secure it in place. You now have a really tiny, slimline wifi addon for your Pi Zero. One thing to note is that the power supply cannot go over 5v, since the 5v test pad is unregulated. I fried the first wifi board I tried, so stay away from using cheap chargers.
