Electronic business card based on ATmega 32u4 microcontroller, the same used on Arduino Leonardo. The Bi-Card is an Arduino-compatible card, with very low thickness, thanks to the use of SMD components. Mounting side connectors (not included), the board can accommodate Arduino shields. It has 5 keys (Browser, Mail Client, Facebook, Twitter, Google+) through which you can recall pre-set addresses by sketch (the card comes pre-programmed with bootloader, the sketch for management as Business Card can be downloaded from Link below).
The power is supplied by the USB port.
The Bi-Card is already assembled and tested

USE

The B-Card is ready for use after it has been programmed with the Sketch. To view the website, or to make P1 effective, open the Internet browser and press P1 in a few moments to access the stored site. The Bi-Card simulates a keyboard and compiles the site characters followed by Enter (the American keyboard is simulated). Similarly, you can also handle other buttons.
