That is indeed a great board. I did a brief look into ESP32 NuttX BLE support and have more questions than answers :) Also the USB host interface is not ported. So I was thinking of picking Orange Pi 3G-IOT-B for prototyping and then go with stage 2 cost reduction with ESP32-S3. My only concern is the security and copy protection, but I found that there is a way to encrypt the file system on Orange Pi, so I suppose that it is a kind of alternative to tamper protection of ESP32 secure boot + flash encryption.
Regarding the computing power, my current estimates are 200MHz CPU with 512K RAM and 2MB should be fine, but I'm still in the research phase.
