usb bc2 PCB Business Card
bc bl PCB Business Card

Brian Carrigan’s clever circuit board business card has Brian’s contact info printed on the PCB and his resume and the project’s source code on the flash chip.

A business card should represent a person’s expertise. My expertise is in creating unique circuit boards, so to celebrate this I wanted to create a USB thumb drive circuit that contains my resume and contact information. This was also a great way to experience coding for USB applications using the Cortex M series of microcontrollers. As a side note, I have done other projects with Cortex M including a simple serial relay and a USB keyboard emulator, but this is the first one that is exciting enough to write about.

While I wouldn’t want to use the final product as my main USB stick, it does exactly what it was meant to do- hold and transfer a small amount of data. The whopping 1MB of storage (maybe I should’ve just used a floppy drive?) allows for enough room to store my resume, a link to my site, as well as the source code for the whole project.
