USBArmyKnife T-Dongle S3

Preconfigured ESP32-S3 USB security lab dongle running USBArmyKnife

USBArmyKnife T-Dongle S3 is a compact ESP32-S3 USB security research appliance built around the LilyGO T-Dongle S3 platform and shipped with USBArmyKnife installed, configured, and tested.

USBArmyKnife is an open-source close-access security testing platform for USB, Wi-Fi, Bluetooth, HID automation, USB device emulation, and payload lab work. This listing is for people who want compatible hardware already prepared instead of sourcing a board, flashing firmware, configuring storage, and troubleshooting the first boot themselves.

This is not a general-purpose hacking gadget. It is a dedicated USB security lab tool for authorized testing, education, demos, and research environments.

Choose your hardware style

T-Dongle with display

The display version uses the LilyGO T-Dongle S3 with a small color screen for visual feedback, status display, and payload/demo workflows that benefit from on-device UI.

Choose this version if you want:

• On-device status visibility
• Demo-friendly visual feedback
• Easier lab use
• USBArmyKnife features that use screen output
• A more obvious “dev tool” look

Covert T-Dongle — no display

The no-display version uses the displayless T-Dongle form factor for a cleaner, lower-profile USB dongle setup.

Choose this version if you want:

• Smaller, less flashy hardware
• No screen glow
• A simpler USB-stick style appearance
• Web UI / file-based operation instead of local screen feedback

Note: Some USBArmyKnife examples and workflows are designed around display-equipped hardware. The no-display version is best for users who understand the tradeoff and are comfortable managing payloads through storage and the web interface.

What it does

USBArmyKnife gives you a small ESP32-S3 platform for learning, testing, and demonstrating USB and wireless security concepts in controlled environments.

Depending on configuration, payloads, and storage, USBArmyKnife supports workflows such as:

• USB HID automation using DuckyScript-style payloads
• USB mass storage emulation
• USB network device emulation
• Local web interface for payload management
• Payload storage on microSD
• Wi-Fi and Bluetooth research features through ESP32-based tooling
• Lab demos, training exercises, and authorized red-team practice

Why a prebuilt unit is useful

USBArmyKnife is open source, but setup normally requires buying compatible hardware, flashing firmware, preparing storage, checking boot behavior, and confirming that the web interface and payload system are working.

This unit is prepared as a ready-to-use hardware platform:

• Compatible T-Dongle S3 hardware
• USBArmyKnife installed
• Basic boot test completed
• microSD option available
• Compact USB form factor
• Ready for lab setup, training, and authorized testing

SD card required

USBArmyKnife uses microSD storage for payloads, configuration files, logs, and examples.

If you do not already have a compatible microSD card, choose one of the SD card options with your order.

Built for security labs and field kits

This is a compact USB research tool for people who work with physical access, USB behavior, HID automation, payload testing, and security education.

It is especially useful for:

• Penetration testers working in authorized environments
• Red-team operators with written permission
• Cybersecurity instructors
• Hardware security researchers
• USB gadget developers
• ESP32-S3 experimenters
• Wireless security hobbyists
• Lab builders and demo kit makers

What’s included

Depending on selected options:

• LilyGO T-Dongle S3 hardware
• Display version or no-display covert version
• USBArmyKnife installed and tested
• Basic boot verification
• Optional microSD card
• Basic getting-started notes

Important notes

This device is for lawful, authorized, and ethical security work only.

Do not use it on computers, networks, accounts, or devices you do not own or have explicit permission to test. Do not use it to steal data, capture credentials, evade monitoring, disrupt systems, bypass access controls, or interfere with communications.

USBArmyKnife is powerful because it can emulate USB behavior and automate actions. That also means it must be handled like a real security testing tool, not a toy.

Features depend on firmware version, selected hardware, microSD configuration, payloads, host operating system behavior, and the user’s own scripts. Some examples from the upstream project may require additional setup or may not apply to every hardware variant.

All orders ship USPS with tracking. Orders usually ship in 72hrs with exceptions for US holidays.
