Kein Bluetooth.

Das stimmt. Dafür aber

and interestingly full-speed USB OTG support.

A Comparison of the New ESP32-S2 to the ESP32 | ESP8266

A short excerpt which sparked my interest:

But the best feature about this new microcontroller is the ULP co-processor based on the RISC-V architecture. That should mean very low power consumption and more processing power compared to the one in the ESP32. The ESP32-S2 is also capable of dynamically turning off the Wi-Fi transceiver when not in use to save power. This allows for low power even with the Wi-Fi “on” pinging the router.

The datasheet talks about a low power mode of just 5uA (!!) and 24uA at 1% duty cycle. That means you can finally have a battery-operated Wi-Fi-enabled device — something not really feasible with previous versions (you don’t want to change batteries every week, do you?).
