OpenNextion ESP32 Marauder is a WiFi/Bluetooth network penetration and defense tool that helps you scan surrounding WiFi and Bluetooth devices, analyze the network environment, and identify potential security risks. Whether you need to conduct on-site signal inspections, detect suspicious devices, or simply gain a clear picture of the actual wireless networks around you, this tool provides intuitive data feedback. With the support of the OpenNextion touchscreen, all operations can be performed by tapping the screen—no computer or external keyboard required—making the detection process more flexible and efficient.
| Feature | Description |
|---|---|
| WiFi Scanning | Scan surrounding WiFi networks to view signal strength, encryption type, MAC address, and other information. |
| WiFi Packet Capture | Capture WiFi packets for network analysis. |
| WiFi Probe Detection | Detect nearby device probe requests to understand which devices are searching for networks. |
| Bluetooth Scanning | Scan for surrounding Bluetooth Low Energy (BLE) devices. |
| Bluetooth Data Capture | Capture Bluetooth communication packets. |
| Attack and Defense Tools | Includes various WiFi/Bluetooth security testing functions (please use only in authorized environments). |
| SD Card Storage | Supports saving scan data and captured packets to an SD card. |
Before starting, ensure the USB cable supports data transfer and maintain a stable connection between the board and your computer.
After successful flashing, the board will automatically restart and boot into ESP32 Marauder.
After flashing, the device will automatically start the ESP32 Marauder interface.

The screen is divided into three touch areas (upper, middle, lower) by dividing lines. The operation methods are as follows:
Scanning Interface
ESP32 Marauder is a WiFi/Bluetooth security testing toolset that runs on the ESP32. It can scan surrounding wireless devices, capture packets, and detect network security risks. Think of it as a "network environment detector" that helps you understand the WiFi and Bluetooth devices around you.
The original ESP32 Marauder supports multiple ESP32 devices, but OpenNexion screens require specific hardware adaptation. This project is specifically adapted for two OpenNexion screens (ONX3248G035 and ONX2432G028), allowing you to operate directly on the touchscreen.
No. You just need to click the "Online Flashing" button at the top of the page to use it. Only if you want to modify the code yourself will you need to set up a development environment.
ESP32 Marauder is a security testing tool designed to help users understand and analyze their own network environment. Please use it only on networks and devices that you are authorized to test. Unauthorized use may violate laws and regulations.
The SD card is used to save scan data and captured packets. If you need to save analysis results, it is recommended to insert a MicroSD card.
The device can be used handheld. Simply connect an external lithium battery to the BAT interface to power the device, and then you can move it freely as a portable control terminal.
The project author has designed a matching 3D-printed enclosure, which will be released for free on MakerWorld. If you don't have a 3D printer, you can use a third-party printing service, or simply use the bare board.
