If you've been following the world of portable pentesting tools, you know the Flipper Zero reigns supreme. But for the makers among us who prefer "built not bought," a serious contender has arrived. Creator CiferTech has just released the ESP32-DIV V2, a completely open-source, multi-band wireless testing toolkit that aims to be a more accessible and customizable alternative to commercial tools.
Wi-Fi and Bluetooth Capabilities: For standard wireless protocols, the device offers a suite of practical tools. On the Wi-Fi side, it features a "Packet Monitor" that can log network traffic to an SD card for analysis on a PC, as well as tools to test network security like a Captive Portal. For Bluetooth (BLE), it includes a "Rubber Ducky" mode, which allows the device to act as a keyboard and execute scripts, and a "Sour Apple" feature that tests how Apple devices handle specific advertising packets.
Radio Hardware and Sub-GHz Control: The physical design consists of a main board with a 2.8-inch touchscreen and a separate radio "shield" that connects using slim pogo pins. This shield is equipped with three NRF24 modules and a CC1101 transceiver, which enables the device to work with Sub-GHz frequencies often used by older hardware like garage door openers and gates. It also includes an Infrared (IR) receiver and transmitter, allowing users to capture and replay signals from standard TV or AC remotes.
Project Availability: Because the project is entirely open-source, it is fully accessible for anyone interested in learning about wireless security or electronics design. CiferTech has released the PCB schematics, 3D-printable case files, and the firmware source code publicly. This allows community members to build the device themselves, study the code, or modify the hardware to fit their own specific needs. You can find the full repository on GitHub to get started.
My only concern is the reliance on a resistive touchscreen, which can feel a bit dated. I really hope a future update or a community fork brings capacitive touch support for a much smoother experience.
