I think it’s mostly for prototyping your own programs, which I haven’t tried yet. It comes with a wifi ssid snooper, and a like greeting card voice recorder/replayer. It’s credit card size, half inch thick. The back half is a removable battery expansion. The stamp has a usb c for data/charging. There’s WiFi, infrared blaster, sd card slot, expansion ports for other sensors. It’s nifty for sure, maybe someday I’ll find a use for it too.
