A Raspberry Pi Pico W-based business card design

Clovis Fritzen is entering the Hackaday business card contest with a novel design built using a Raspberry Pi Pico W.

The above image is of my project, which I already sent to PCB manufacturing. It features a Raspberry Pi Pico W (with Wi-Fi) to the right and a touch button in parallel with a mechanica switch for “wake up” functions. To the right there is a 6×6 charlieplexed LED display (using only 7 pins of Pi Pico) and a 0.96″ OLED yellow/blue display.

My plan is for the card to be in a “dormant” state where it will show time (hour and minutes) and temperature in binary on the LEDs, fetching such data from a web API. The OLED display will be displaying contact information.

When you press the touch button or the mechanical switch, the charlieplexed 6×6 LED display will probably show your e-mail (letter by letter). The OLED display will probably show more contact information in a “rolling” style.

See the design here, PCB files on GitHub and the hackaday.io page.
