Linux-based PC fits into your business card?

In order to make a unique business card, they even make it possible to use the business card as a USB memory. However, this time, a business card with all the minimum components necessary for a PC such as a CPU and memory appeared and attracted attention.

It was George Hilliard, an embedded systems engineer, who created the Linux-based PC business card. He put a profile on the surface and marked this card as running Linux! An IC chip was installed at the bottom of the business card. The business card itself is being used as a substrate.

The card has a USB port, so when connected to a PC, you can access storage containing his resume and facial photos. In addition, if you run the shell through the virtual serial port, you can use the Unix program Fortune, which plays games 2048 or logs, randomly displays quotes, and a micropython interpreter for processing programming languages.

The material cost per sheet is 1.42 dollars for the Allwinner SoC, F1C100s, 0.8 dollars for the PCB, 0.17 dollars for the 8MB flash chip, and 0.49 dollars for other components. However, as it is handmade, it takes time, so he does not plan to distribute it to everyone for free.

What he uses for soldering is a reflow oven (Puhui T-962). This product has the advantage of being inexpensive. He said that he used his experience in designing embedded Linux systems and printed circuit boards. “It’s not perfect, but the project itself has been a good experience.” Related information can be found here .
