“Small, and with the onboard radio kit I can use as a Wi-Fi enabled serial server using hostapd and ser2net together with a suitable usb terminal adapter.”
“What can you say about the 0! Tiny, takes very little power and packs a punch above it's weight! With the Pirate audio hat, makes a handy little wireless satellite sound system.
So many projects for these, personally, I use them as a PiHole, in a GPi case for on-the-go retro gaming and for tiny, portable sound systems.
The Pi Hut delivers yet again!!”
“Great little device if you are looking for a low powered Linux machine! Easy to setup (search the interwebs to find out how to setup WiFi on first boot as well as ssh).”
“A great device for developing embedded projects. I've used mine to prototype a web stream player for hospital radio, and to drive a confidence screen for a band so that they have song lyrics on a screen that can be paged back and forth using a bluetooth foot switch. I'm sure I'll find plenty of other uses too.”
