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.
