OMGS3 is the world’s smallest, fully-featured ESP32-S3 microcontroller board/module!
OMGS3 is the world’s smallest, fully-featured ESP32-S3 microcontroller 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 from this store ship directly from me here in Melbourne, Australia. Orders are processed daily and usually go out within a few days! I'm currently unable to ship to Germany, Denmark, or Sweden, but I am doing my best to work with Australia Post and Zonos about this issue; sorry for any inconvenience. Finally, postage rates suck, and they keep going up; sorry :(
