USB business card

This PCB designed to be used as a USB business card. It uses a ATtiny85 with VUSB which converts it to a HID. The PCB itself integrates a male USB plug. It’s connected on a computer or an Android USB OTG and is being identified as a keyboard.

We open a text editor and we use the 3 buttons to print text on the screen. The buttons print my website address, my email address and my phone number.
