This device is similar to many hacker festival badges from the recent years. Just a bit more expensive.

For example:

- the Camp 2023 flow3r badge https://events.ccc.de/2023/06/05/camp23-the-flow3r-badge/

- the MCH2022 badge https://wiki.mch2022.org/Badge

- the SHA2017 badge with E-Ink https://wiki.sha2017.org/w/Projects:Badge

- the Camp 2011 badge R0ket https://events.ccc.de/camp/2011/wiki/R0ket

The first three have ESP32 CPUs, not sure how it compares to the ARM Cortex-A35
