An easy way to add a Wi-Fi module to your Raspberry Pi Zero

It doesn’t look very good, but it works!

Only a few days passed after the Raspberry Pi Zero went on sale , and there were already craftsmen who expanded the capabilities of this mini-PC. A user with the nickname Shintaro was able to add a Wi-Fi wireless module to the main module. He did it simply - soldered Edimax WiFi USB Adapter. Connection was made to the USB-contacts of the board.

The user removed the adapter housing. Power for the module is taken from pins PP1 and PP6 on the back of the board. These are unregulated power outputs via USB, so you should work with them carefully so as not to damage the connected equipment or the ay itself. Some inexpensive USB adapters can supply more than 5V, which is fraught - the whole circuit may burn out.



Data is transmitted to and from the module through PP22 and PP23, they are also located on the back of the board. The wires by which the module is soldered to the board must be of the same length in order to avoid signal distortion. An SD card was prepared on the Raspberry Pi B 2 to configure user data.

Features mini-PCs are as follows:

• Processor: ARM11, Broadcomm BCM2835 at 1 GHz
• Memory: 512 MB RAM
• Storage: microSD
• GPIO: 26/40 holes
• USB Connectors: USB On-the-Go (OTG), Micro USB
• Video output: composite video through two pins on the board (marked as TV), HDMI via mini HDMI connector (1080p60)

Unfortunately, there is no more information about the project, but the modification itself is not too complicated, so everything is clear. Information about the project is posted here on this page .
