Pretty cool, right? A business card made out of fiberglass, copper, and (not)lead RoHS. What does it do other than just look cool or make your friends wonder why you're walking around with it like a nerd?

Whether you want to become involved in the world of IoT development or you are just the O-est of G's and need the sickest business card on the block, the ESP8266 Business Card is a fun way to learn a little bit more about what goes on in the MountainDew dungeons of beta-males everywhere.
Make home automation tools. Disable your neighbor's WiFi. Make a WiFi enabled music visualizer that only responds to voice commands in Vietnamese. I don't care what you do with this hunk of junk as long as you enjoy messing with it.
