How would you ever actually practically use this

[–] Cocodapuf@lemmy.world 3 points 3 hours ago

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.

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.

[–] catloaf@lemm.ee 35 points 20 hours ago

Same way you would in any other microcontroller application, but smaller, so the whole device can be smaller.

Get small enough and we can really have those bloodstream robots.

Maybe an actual useful smart ring?

fly-sized spy drone

In small things. Probably not very feasible for hobby projects unless you can get it soldered on when the PCB is built.

[–] MartianSands@sh.itjust.works 8 points 19 hours ago (1 children)

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)

[–] Manifish_Destiny@lemmy.world 2 points 10 hours ago

This is already technically hand solderable with the right equipment.

[–] Beacon@fedia.io 9 points 20 hours ago

In any use where size and or weight is important. For example wearables and flying drones
