There is a SDR device for hacking that is self-contained. It's the HackRF+Portapack, (https://hackerwarehouse.com/product/hackrf-one-kit/ https://hackerwarehouse.com/product/hackrf-one-kit/) - which costs significantly more. It uses a FPGA to decode raw signals at up to 6GHZ. The Flipper uses dedicated chips to decode the specific protocols, with each chip having a specific protocol (NFC, LF RDID, 433/900Mhz), which allows a general purpose CPU to interface with other devices.
