## Description

The WiFi Devboard for Flipper Zero is an ESP32-S2-powered expansion board that adds WiFi connectivity to the Flipper Zero multi-tool. Designed by Flipper Devices, it plugs directly into the Flipper Zero's GPIO header and unlocks wireless firmware updates, eliminating the need for a USB cable during development. The board runs the Black Magic Probe open-source debugger firmware, enabling advanced in-circuit debugging of the Flipper Zero's STM32 microcontroller via both USB and WiFi interfaces.

Beyond development workflows, the WiFi Devboard serves as a platform for WiFi security research and penetration testing. With compatible firmware like ESP32 Marauder, it can perform PMKID hash capture, deauthentication attacks, and wireless network scanning — making it a versatile tool for security professionals and researchers. The board can also connect the Flipper Zero to the internet, opening up possibilities for remote control and cloud-based features.

The hardware is built around Espressif's ESP32-S2 single-core Xtensa LX7 microcontroller running at 240MHz, featuring 320KB SRAM, 4MB flash, and 802.11 b/g/n WiFi. It connects to the Flipper Zero via the GPIO header and includes a USB-C port for direct programming and power. The entire Flipper ecosystem is open source under GPL-3.0, with schematics and firmware publicly available on GitHub, encouraging community contributions and custom firmware development.
