Story

This project is a hardware hacking toolkit using an ESP32 microcontroller that allows you to interact with RS485-based systems — commonly used in industrial automation, building control (e.g., elevators, HVAC, door systems), and legacy equipment. It includes: • Dual RS485 transceivers • WiFi interface via mobile app • Hex-level sniffing and injection • Preset command storage • Baud rate configuration • History logging ? Why RS485? RS485 is widely used in critical systems — but often lacks encryption or authentication. This makes it an excellent candidate for research, diagnostics, and security testing. From industrial MODBUS networks to unauthorized door controllers, there are tons of real-world applications.
