    Security tools like Flipper Zero are essentially programmable radios, known as Software Defined Radios (SDRs), a technology which has existed for years, and in some cases can be built using open-source or simple over-the-shelf-components.

      SDR? I thought it just had a CC1101 for sub-GHz digital and an NFC/RFID module? CC1101 is very flexible but it doesn’t do direct IQ sampling.
