## Description

###OMGS3 is the world’s smallest, fully-featured ESP32-S3 microcontroller board/module - just drop it on your PCB and focus on your features!

It can also be used without a carrier PCB if you want to solder wires directly to it, for those tiny little projects that need the smallest of boards!

## Shipping policy

All products purchased on this store ship directly from me here in Melbourne, Australia.

Orders are processed daily and usually go out the same day they are paid for - allowing for time zone differences of course.

Finally, postage rates suck, sorry :( I'm embarrassed by how much it costs to ship items overseas since COVID, and I do my best to improve rates where I can.

Postage delivery times, if stated, are based on current expectations from Australia Post and may vary.

Please keep in mind that there are still occasional postage delays, including flights out of Australia and inbound customs processing into many countries.
