Frustrated with the OuterNet SDRx 1v10

When I purchased the OuterNet SDRx 1v10 and the antenna, the shop still says that works and you can “SDRx can be plugged directly into a single board computer, such as the Raspberry Pi”. But everything I read says that this doesn’t work anymore? How do I get this to work?Is the CHIP the only option and which chip?I feel frustrated that I have to wait for more hardware before I can start using the Outernet!
