CyberPhone: Dual-Brain Advanced Communication & Power Hub
Dual-brain (ESP32 + STM32) integrated system for 15km radio, phone calls, and high-capacity portable power.
A revolutionary dual-microcontroller hub that bridges high-range radio communication, smart phone functionalities, and emergency power generation into a single portable unit.
CyberPhone is a masterclass in embedded systems integration, combining the high-performance capabilities of the ESP32 and STM32 microcontrollers to create a "dual-brain" architecture. This project features long-range NRF radio transmission reaching up to 15km, enabling free message exchange in remote areas. The device is also a fully functional smart communication tool, handling phone calls through dedicated audio outputs and integrating WiFi/Bluetooth for seamless connectivity.
