- 1Hidden SDR Capabilities Discovered in ESP32 Microcontrollers●Various Projects Find Hidden SDR Capabilities in ESP32 Microcontrollers
Multiple independent projects have discovered that the widely used ESP32 microcontroller contains previously undocumented software-defined radio capabilities. The finding means millions of cheap, common chips can potentially receive radio signals without extra hardware, opening up low-cost wireless experimentation for hobbyists and developers. Engineers are discussing the technical details and possible applications of the hidden functionality.
