Espargos

A project called ESP-SDR enables raw IQ capture using Espressif's ESP32 chips, effectively repurposing the ubiquitous low-cost Wi-Fi microcontrollers as a software-defined radio. Developed by the Espargos team, it lets hobbyists sample wireless signals directly with inexpensive off-the-shelf hardware. Engineers and radio enthusiasts are discussing the technical achievement, since dedicated SDR hardware normally costs far more than an ESP32 board.
