Ah, I did not know that. I've always worked with USB SDRs, is a regular USB3 higher bandwidth than these pins?

- blihp 5y agoUSB 3 can provide orders of magnitude (how much depends on which rev) more bandwidth. This device provides slightly more bandwidth than an RTL-SDR stick over USB 2.
- jcrawfordor 5y agoUSB2 can do 10MSPS easy, but in my experience small SBCs like the Raspberry Pi struggle to keep up with this rate at the CPU. Might be more practical with the newer models, but I gave up on an RPi 3 with a 10MSPS SDR because it was excessively dropping samples at around the 5MSPS point... so it's possible that 4MSPS is approaching the limit of the CPU, at least for a given level of optimization of the software tools (I was mostly just sending out I/Q samples over the network).
