ESPARGOS/esp-sdr
ESP-SDR uses the undocumented raw I/Q capture functionality of ESP32 family chips to turn them into (low-duty-cycle) Software Defined Radios
ESP-SDR is firmware that turns ESP32-family chips into low-duty-cycle software-defined radios by using an undocumented debug path to access raw I/Q samples from the built-in 2.4 GHz Wi-Fi receiver (5 GHz on ESP32-C5). Samples are streamed over USB/UART or processed on-device, viewable in a browser-based SDR viewer, with no separate SDR hardware needed.
Why now: Recently trending on GitHub (most-starred new repos), notable for discovering an undocumented hardware debug path and for heavy use of LLMs to port IQ sampling across the ESP32 family.
Who it is for: Radio hackers, SDR hobbyists, and embedded developers who own ESP32 boards and want cheap spectrum-analysis and signal-capture capability.
