Multiple independent projects have discovered hidden Software Defined Radio (SDR) capabilities in ESP32 microcontrollers, enabling RF reception beyond their intended design. This finding opens new possibilities for hobbyists and makers who can leverage the widely available, low-cost ESP32 chips for radio signal experimentation and interception.
Background
The ESP32 is a popular low-cost microcontroller by Espressif Systems widely used in IoT and maker projects. The chip has built-in WiFi and Bluetooth but was not originally designed or advertised as an SDR platform.
