TechKeys is serious about custom keyboards, and to prove it, they created a business card that is a functioning keyboard.  This PCB with on-board re-programmable ATMEGA16U2 improves upon the previous version making it even more fun for hackers, tinkerers, and makers.  The card has a 7x24 LED matrix allowing for default software that makes 4 keys programmable to even the most basic users.  Take home one of these as a project, keycap display, switch tester, or a shortcut to yours truly, TechKeys.us.  Full demonstration coming soon.

Assembled option comes with 4 Gateron Blue Switches soldered onto the board making it ready to plug in and go.
