The official Wi-Fi Dev Board (ESP32-S2) attaches to Flipper's GPIO header and adds Wi-Fi capabilities. Here's how to set it up and what it unlocks.
Hardware
The official board is: Flipper Wi-Fi Dev Board (Flipper Devices) Community alternative: ESP32-WROOM or ESP32-S2 DevKit with GPIO wiring
Connecting the Official Dev Board
- Align the board with the GPIO header on Flipper's back
- Press firmly until seated
- The board gets power from Flipper via the GPIO 5V pin
Flashing Marauder Firmware (Most Popular Use)
Marauder is a Wi-Fi security tool for the ESP32:
- Visit github.com/justcallmekoko/ESP32Marauder/wiki
- Download the Marauder firmware for ESP32-S2
