What is it?
Deauther Mini is a portable WiFi penetration testing development board specifically designed for cybersecurity research, education, and geek enthusiasts. It is based on the popular ESP8266 chip and pre-installed with the renowned Deauther firmware written by Spacehuhn.
No complex code configuration is required. Just press a button and you can visually test and explore the vulnerabilities and mechanisms of 802.11 wireless networks in the palm of your hand. It is the perfect “entry-level” hacking hardware for you to understand WiFi security and enhance your awareness of protection.
Deauther Mini originated from the nodemcu development board. You can still regard the latest V4 version as an improved NodeMCU development board.
Key Features
Deauth (Disconnection Testing)
Forcefully disconnect specific devices from their WiFi connections by sending spoofed deauthentication frames to the target router and devices. Ideal for testing network resilience and defense mechanisms.
Beacon (SSID Flooding)
Instantly generate dozens or even hundreds of fake WiFi network names (SSIDs). This can be used to obscure your actual WiFi network or broadcast specific messages to nearby devices.
Probe (Probe Request Spoofing)
Send fake probe requests to confuse WiFi trackers, or observe the signals devices emit when searching for known networks to gain a deeper understanding of device connection behaviors.
GPIOs and hardware info:

Hardware Highlights: Compact yet Powerful
- Ultra-Portable Design: A true “pocket-sized” gadget. Whether you are testing at a local cafe or demonstrating at a cybersecurity conference, it’s easy to carry and always ready to go.
- Intuitive Visual Operation: Equipped with a high-contrast OLED display and onboard physical buttons/scroll wheel. You can navigate menus and execute tests independently without needing to connect a PC or smartphone.
- Excellent Expandability: Features an onboard power management system that supports direct LiPo battery connection and charging. The external antenna interface allows you to easily swap in high-gain antennas to drastically expand your signal coverage.
- Open-Source & Programmable: It’s not just a testing tool; it’s a standard ESP8266 development board. You can use the Arduino IDE for secondary development and flash your own custom firmware. You can find schematic from https://github.com/lspoplove/DeautherMiNiV4/blob/main/Sheet_deautherMiNiV4.pdf
Target Audience
- Cybersecurity Students & Educators: An intuitive, hands-on teaching aid for demonstrating WiFi protocol vulnerabilities.
- Geeks & Makers: Perfect for exploring the underlying logic of wireless communications and experiencing the fun of DIY hardware.
- Network Administrators: A practical tool for testing the stability and attack resistance of their own network environments.
