There is a similar device from lilygo which has an ESP32S3 plus also a SDCard slot all in one USB stick. It is available all over Aliexpress for around $10.
You do have to code it yourself if you want to display information on it. However it has all the goodies of the ESP32S3 which is a very powerful MCU with wifi and bluetooth.
For fun I ported my railway station display [2] firmware which also runs on a ESP32S3 to it [3]. Cool little gadget.
