Flipper Zero Wifi Devboard - WiFi

Flipper Zero Wifi Devboard is a module that extends the capabilities of the Flipper Zero device with WiFi communication. It is based on the popular ESP32 -S2 system, with one Xtensa LX7 core clocked at up to 240 MHz, 2 MB RAM and 4 MB Flash. It allows you to wirelessly debug and change the Flipper Zero software. The built-in USB C connector allows the module to be used as a USB-UART converter. Data exchange between devices takes place via the SWD interface, and the remaining GPIO pins are placed on the board, along with additional Reset and Boot buttons for the ESP32 system.

Flipper Zero WiFi Devboard allows the user to update the device's software via WiFi communication or the USB C port. Additionally, the board can be used to debug the currently executing program. For this purpose, the ESP32 module uses the SWD interface present in Flipper Zero to read logs and manipulate the program's operation (setting breakpoints, viewing memory contents, etc.). It works as a GDB server (GNU Debugger), enabling data exchange with a computer via USB C or the WiFi network created by the module.

More advanced users can also use the capabilities of the built-in ESP32 chip to perform analysis and penetration testing of WiFi networks. However, this functionality has not been implemented by the manufacturer.
