PCB Studios has just launched the “Flipper Zero ESP8266 Deauther” adapter board for Flipper Zero that enables users to conduct de-authentication attacks on Wi-Fi networks. Running a modified version of SpacehuhnTech’s ESP8266 Deauther software, this board has a variety of actions for testing 802.11 wireless networks. Its primary function, deauthentication, sends deauthing packets to the target network, disconnecting devices from their 2.4 GHz Wi-Fi networks.
In our last post about Flipper Zero, we wrote about Flipper Add-On CANBus a CAN bus hacking tool that can sniff, send, and log CAN bus packets. Other than that we have seen similar tools like the M1 multitool and HackBat which can be considered as Flipper Zero alternatives with STM32H5 and Raspberry Pi RP2040 MCUs and Wi-Fi connectivity. We have also written about various ESP8266 and ESP32-based Deauther tools like the DSTIKE Deauther Watch X, the Cheap Evil Tech Deauther board, and ESP32 Marauder Pocket Unit v2 all of which are wireless penetration devices. Feel free to check them out if you are interested in those topics.
The board can be considered a GPIO board and a standard ESP8266 NodeMCU module sits on top of that PCB, so there is an option to buy the PCB only or the PCB with a soldered NodeMCU ESP8266 module on top of it.
PCB Studios mentions that to use this board, you must have the Flipper Zero app; however, if you are using firmware such as Rougemaster or Xtreme, the application comes preinstalled. Otherwise, you need to follow the instructions on GitHub to install the app, and as far as I understand, there is no way to install the app through Flipper’s app store.
This software allows you to easily perform a variety of actions to test 802.11 wireless networks including scan, attack, Packet monitor, and more which makes it a versatile tool for penetrating testing applications.
The Flipper Zero ESP8266 Deauther is priced at around $24.98 with the soldered ESP8266 module and $19.99 without the soldered module, both boards are available at the Tindie store.

“For security and research” 🙂 For sure! It’s well known that deauther (and flipper zero to some extents) are mainly used for security and research, not just to have fun with insecure stuff! That’s the radio version of the old venerable tv-b-gone which was aimed at studying the security of TV IR codes by trying to shut down as many of them as possible in a minimum amount of time 🙂
Deauthing (and handshake capture as a result) only works when management frames are not protected. For WPA3 it’s mandatory, for WPA2 PMF is optional
Why the really old esp8266? There are modern esp32-c6 chips out there.
Because it’s inexpensive and works?
The esp8266 has been available as an addon board sold alongside the flipper since launch, this new addon board has no extra features, why write this article?
