I made a showcase video for the ESP32-S3 PowerFeather. This showcase includes a hardware tour, power features & capabilities overview, and some demonstrations. Please do forgive the production quality - since I don't have the setup to do this kind of stuff!

For those who want a written version of the demonstrations, I've made an article on Electromaker and Hackaday on it.
I've also written an article on why ESP32-S3 PowerFeather came to be on Hackaday.
