It is useful for beginners learning about RF, NFC, RFID, infrared, GPIO, and cybersecurity concepts. Some advanced functions may require technical knowledge or firmware setup. Does the range always reach 250 meters? No. RF range depends on the antenna, environment, obstacles, signal type, firmware, and local restrictions. The listed range should be treated as a best-case testing condition, not a guaranteed result. Can I install custom firmware? The device is designed for open-source firmware experimentation. Compatibility depends on the exact firmware version and device configuration. What is this device used for? It is intended for education, authorized signal analysis, hardware research, and cybersecurity learning. Do not use it on systems, devices, or signals without permission. SHARK is intended for educational, cybersecurity research, and authorized testing use only. Always follow your local laws and only test systems, devices, or signals you own or have permission to analyze.
