These products provide firmware, specialized boards, and software utilities for microcontrollers like the ESP32 and software-defined radio (SDR) applications. They are built for hardware hackers, embedded engineers, and security researchers exploring wireless signals and custom electronics. This cluster is distinguished by its focus on low-level hardware prototyping, signal processing, and physical-layer networking rather than pure cloud software.
