A project called ESP-SDR demonstrates using Espressif's ESP32 chips to capture raw IQ samples, effectively turning the low-cost Wi-Fi microcontrollers into a software-defined radio. The project, published by developer Jeija via Espargos, is drawing attention among hardware and radio enthusiasts on Hacker News, where it reached the front page. Commenters are discussing the technical feat of extracting raw signal data from consumer-grade chips.
