I got a Lilygo T-Dongle S3 yesterday, which is an ESP32-S3 in USB thumbdrive form factor, it's got some quite interesting use cases.

The project that got me interested in it is this: https://github.com/i-am-shodan/USBArmyKnife

It turns it into a souped-up rubber ducky, with networking and serial capability. What I really want to allow it to do is bridge usb networking and wifi to create an out of band network to run network attacks from another device (like my phone)
