I've often wondered why someone doesn't design a daughterboard with a SDR chip for the RPi as this would let them do away with the embedded cpu/FPGA.
Plunk an rtl-sdr chip on a RPi board and Bob's your uncle...
- derefr 8y agoPerhaps the IO bandwidth between the RPi and its peripherals isn't high enough to enable it to manage an SDR. (I don't imagine you could connect a modern GPU, or a video capture device, to an RPi either.) Speaking of: are there any SBCs that have PCIe-based daughterboard support? Or Thunderbolt-3-based peripheral support?
- namibj 8y agoThose based on the Zynq-7000 line from Xilinx usually have ample IO, but start at about 100$, going up. You might need to do something in the FPGA part of them to use the IO though.
