World's smallest microcontroller looks like I could easily accidentally inhale it but packs a genuine 32-bit Arm CPU
World's smallest microcontroller looks like I could easily accidentally inhale it but packs a genuine 32-bit Arm CPU
A sneeze-inducing 1.38 mm² and small enough to make a Raspberry Pi look like a bus.

How would you ever actually practically use this
-
Maybe an actual useful smart ring?
-
In small things. Probably not very feasible for hobby projects unless you can get it soldered on when the PCB is built.
-
BGA, like in the photo, isn't the only option. There are options only slightly larger with hand-solderable packages (if you're good at soldering)
-
This is already technically hand solderable with the right equipment.

-
In any use where size and or weight is important. For example wearables and flying drones
-
fly-sized spy drone
-
Wrist watch.

I make specialty vehicle electronics. My immediate thought was very small and cheap sensors. Similar to tire pressure monitoring but wired with CAN or something similar.
-
You could use it as the logic board for a micro drone, something the size of a dime perhaps. Or other applications where weight or space are extremely limited. Another example might be a medical implant of some sort, this is small enough that it could be a part of a device that is meant to be placed inside an artery, or an eyeball, or an ear canal.

see comment from @Lumberjacked (it is complicated !)
