What If Your ESP32 Could Become an SDR?
ESP-SDR turns supported ESP32 boards into a small software-defined radio receiver.
It gives you access to raw IQ samples from the Wi-Fi radio, letting you see the 2.4 GHz spectrum and waterfall in a browser.
You can explore things like RF signals, spectrum analysis, IQ data and wireless interference without expensive SDR hardware.
The ESP32-C5 is even interesting here because it can work in the 5 GHz band.
A tiny development board suddenly becomes a great tool for learning RF and signal processing.
