The Flipper Zero has the option to attach different peripherals to it's GPIO headers. One such option is the ESP32-S2 Development Board which provides the Flipper Zero with the hardware required for WiFi capabilities. The Marauder firmware can be installed on the ESP32-S2 either via prebuilt firmware binary uploaded over-the-air(OTA) or via configured source build and upload. For either process, it will be assumed the connection between your PC and your WiFi dev board is "direct" i.e. you are not using the Flipper Zero USB-to-UART bridge. Once the install is complete however, you will be required to use the Flipper Zero USB-to-UART bridge.
It is recommended to use the Flasher Script option if you choose "Blue Pill" as this is the quickest and most direct method for installing the Marauder firmware on your WiFi Dev Board
If you do not currently own a 3D printer and would like to purchase an enclosure for your WiFi Dev Board, I am currently selling them on Tindie with multiple color and material options. If you are interested, check out the shop here.

| Really easy. Nothing to change, but you don't get any customization (which is fine). | This pill is the size of a large pumpkin and it goes in your ass. Install libraries, build from source, know everything |
| Flasher Script or Marauder OTA | Build from source |
Once you install the Marauder firmware on the WiFi dev board, you can connect the dev board to the Flipper Zero GPIO header and connect the flipper to your PC or Android phone via USB cable.
On the Flipper Zero, navigate to GPIO>USB-UART Bridge. I keep my Bridge configured to use USB channel 0
If you are having issues with your Marauder installation either with the install process or with the firmware usage, be sure to check if your issue has already been solved in FAQ. If not, feel free to join my Discord to request help from the community or submit an issue
Marauder can be used via its command-line interface supplemented by the Flipper Zero USB-to-UART bridge and a PC/Laptop. The goal is to eventually get the Flipper Zero to offer a bluetooth connection to facilitate a Serial-over-Bluetooth bridge to the WiFi Dev Board so everything can be done over mobile phone.
If you would like to use the Flipper Zero and it's WiFi dev board flashed with Marauder as a standalone unit without a PC or mobile phone attached, install flipperzero-firmware-wPlugins by RogueMaster on your Flipper Zero. It features an interface directly available on the Flipper Zero menu which allows full control of the Marauder firmware running on the dev board.
A MicroSD card can be attached to the Flipper Zero WiFi Dev Board SPI via a MicroSD Breakout. Attaching a microSD card to the Flipper Zero WiFi Dev Board will allow the Marauder firmware to save captured WiFi traffic to storage in the form of PCAP files to be exported for analysis later. Refer to the following table for the required solder connections
| MicroSD Breakout | Flipper Zero WiFi Dev Board |
|---|---|
| VCC | 3V3 |
| GND | GND |
| DI (MOSI) | IO35 |
| DO (MISO) | IO37 |
| SCK | IO36 |
| CS | IO10 |
Once all of the solder connections have been made, a piece of double-sided tape can be used to fix the MicroSD Breakout Board to the back of the WiFi Development Board.

The following video describes and demonstrates the installation and usage of the Marauder firmware on the Flipper Zero WiFi Dev Board.
