This same devloper also built an SDR out of an ESP32 Wi-Fi microcontroller [1], this is awesome!

This development makes me hope that we'd be seeing more of these on common Wi-Fi cards, so that every random laptop could be used as an SDR for many fun and useful applications on a budget.

It’d be neat to see this on ESP32-C5, which also has a 5GHz radio. S3 is 2.4 only.

I was really excited about this, but as an average home assistant user couldn't really see an application, lol.
