Luca Dentella designed and built a USB stick powered by esp32-s2 chip, the esp32s2Stick:

esp32s2Stick is a USB device based on the esp32-s2 chip by Espressif. Thanks to the presence of an USB OTG interface, it is possible to program the chip to act as a USB peripheral (mass storage device, CDC…) and to upgrade the firmware through USB (DFU, Device Firmware Upgrade).
In addition to the basic circuit needed to run the WROVER module, esp32s2Stick offers an RGB LED and a socket for MicroSD cards.
