maybe I'm blind, but it looks like there's no radio! like there's wifi and bluetooth, sure, but I don't see NFC or RFID or sub-1ghz radio, at all.

imo the flipper always needed to be a software-defined transciever, with a small FPGA to drive it, like the other SDRs on the market. I'm disappointed they seem to have forsaken radio completely.

They added an M.2 port [1] to which you can attach a variety of modules, including SDR (eg. [2] 30 MHz - 11 GHz).

The flipper zero was already in a grey area because it easily enables one to do things in licensed bands and do things you’re not allowed to do in unlicensed bands. They can’t plausibly add even more functions in this area and still sell to the public. Presumably all of the interfaces they added are for users to add the functions under their own responsibility.

I wonder if that means they can sell them on amazon now.

Most likely you will have to buy the M2 adapters, for cellular, wifi, maybe zigbee and others radios, and you will switch between them, it’s also good for their profit but bad for your pocket.
