Soldering my own CUL sender/receiver
Those modules are similar in that they are both RF transceivers, but the second one (the CC1101 module) doesn't have the necessary capabilities built in to be able to 'talk USB' which the first one has.
Its not just a 'missing USB connector' and would need a bit more added on to be able to plug into a PC.
