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 Kailh Blue Switches soldered onto the board making it ready to plug in and go.
