Raspberry Pi enthusiasts that have been enjoying the new extremely affordable Raspberry Pi Zero mini PC might be interested in a new project which has been published to YouTube this month.
YouTuber ‘Node’ has published details on how to add a low-profile wireless board to the $5 Raspberry Pi Zero mini PC, opening up a wider variety of applications and projects available for developers, makers and hobbyists to build.
Check out the video below to learn more about the addition of wireless support to the Pi Zero.
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.
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.
