“Pi Sniffer is a Wi-Fi sniffer built on the Raspberry Pi Zero W. While there are many excellent sniffing platforms out there, Pi Sniffer is unique for its small size, real-time display of captured data, and handling of user input.
Current Release Image
You can download an RPI image of this project from the “Releases” page. If you don’t trust that, you can generate your own release by using the image_gen/create_image.sh script.
Project Goals
The goal of this project was to create a Wi-Fi sniffer that I could carry around in my pocket, easily view real-time status, decrypt packets on the fly, and change antenna channels as needed. Also, I wanted this project to be cheap (less than $100) and require no soldering.
Hardware
The project was conceived with the goal to avoid any type of soldering. While Pi Sniffer does require the GPIO header on the Raspberry Pi Zero W, you can buy that pre-soldered. So I’m gonna claim no soldering required.
The base install requires:
Raspberry Pi Zero WH
Adafruit 128x64 OLED Bonnet
A power source. I suggest one of the following:
Anker PowerCore 5000
Anker E1 Astro
UPS-Lite
Any SD card 8GB or larger
Additionally, you can configure the device with any of the following add-ons (and still reasonably be called pocket sized):
Secondary antenna by CanaKit
Ublox-7 GPS
MicroUSB to USB adapters
USB MiniHub”
