alt Hacker NewsAs far as I follow the research process it's currently quite difficult to get all data (like the 80MSPS@10-Bit showcase on Reddit) to a computer without a FPGA+USB3.
With the new ESP32-S31 we most likely can extract the I/Q data over its new 1 GBit/s interface. Guessing something around 20-40MSPS should work.
These hack will most likely will be a revolution for 13cm ham radio. With the new 5GHz ESP32 modules most likely also for 5cm. As all Espressif components are WiFi-qualified we can expect a very very stable and robust radio.
I ordered a few and waiting for Ali to deliver them to my lab.

No mention what FPGA platform/board used, FT600 USB chip is ~$10 alone.
Now you can replace all of it with one of those silly $5 FX2LP USB 2.0 dev boards. CY7C68013A-56 supports 16bit interface and will happily pump 30MB/s all day long for a fraction of the price. $10 total for 2.4GHz ~12MSPS@10-Bit SDR.
