You should already have the ESP8266 driver installed (link above) and Arduino IDE (also linked above) ready to go. The first thing you need to do, is open up the Arduino IDE and open up the files linked in the GitHub. Once the files have been opened, you should see a file called config.h. In there, you should change the following: your WIFI SSID, WIFI PASS, and CONNECTION STRING. Your SSID and PASS are just the username and password for your home Wi-Fi. Make sure your internet doesn't have any extra steps (for example. account login or redirect) To find your connection string, you must create an Azure IoT Hub. It's pretty simple but if you have trouble, check out this helpful article. Once you have created an IoT Hub, follow these steps to find your connection string. Go to the Azure Portal and find your IoT Hub. On the left side, you should see Shared Access Policies. Then click on Service and you will see four strings. The string titled Connection String -- Primary Key is the one you will want to copy and paste. Make sure you don't share your connection string, it is super important!

Have you looked thru here may be useful. Does this screenshot help?

You can flash the board via the flipper app, or with a pc. Check this out https://github.com/justcallmekoko/ESP32Marauder/wiki/installing-firmware-via-ota

but in release page https://github.com/justcallmekoko/ESP32Marauder/releases/tag/v0.10.8 there is only firmware esp32_marauder_v0_10_8_20230621_flipper_sd_serial.bin

The WiFi marauder CAN connect to an access point and be part of same network as the victim. With some arp spoofing/poisoning you can pull off a basic MITM atk and save the traffic to the flipper SD card. Maybe even print it on the screen to show the audience in real time.
