Pico Wifi Analyzer Phase 1

Aug 2026


Back to Pico Wifi Analyzer with LCD

There is a lot of information on this Wiki about how to build this project, but don't be fooled, it's a very simple project, and it will take you longer to read the Wiki than it will to build the project :)

I recommend you read all the wiki pages for this project first so you don't miss something important or order some parts that will not work.

The project consists of a Raspberry Pi Pico, an LCD Screen, 4 Wires and a pre-written Python script, very simple. The hardest part of this project will probably be getting a compatible LCD, if you look on Aliexpress, there are hundreds of these LCDs and they cost between £2-£3 each. Buy two in case you break one :) The LCD I have used is I2C, this is important because the Driver file and the running software are all setup to use I2C.

Before starting this project you must complete the following four tasks, that are on this Wiki, but I will link you them, and they are:

• Using Pico with SSD1306 based I2C LCD - This will show you the wiring for the LCD, and how to do a quick test.
• Connect Pico to Wifi - This is a must, you have to have Wifi connectivity, this will let you test this.
• Find Pico MAC Address - You don't need this unless your router uses MAC Address Filtering.
• Check Device I2C Address - You need the I2C address from your LCD to put in to the Python script.

Phase 1 - Prerequisites
Phase 1 - The Wifi Analyzer Software
Phase 1 - A quick explanation around the UI and Operation
Phase 1 - 3D Printed Enclosure

That is it, you should now be all done and have a working Wifi monitor device. Well done :)
