Ever since I have my own company I wanted to have a PCB business card. Of course I wouldn’t be the first, but it would definitely give a nice touch to my company’s identity. And since I wanted to give KiCad a good try anyway, why not go for it?
Of course it’s fun to just make a fake pcb layout, but it would be even better if an assembled version of my business card really had some nice features. Since I managed to get a bare SSD1306 OLED working, there wasn’t any excuse to not accommodate the business card with an OLED display.
I wanted to add a nice easter egg. I already programmed Pong once. But with the 3 push switches and the width 128x32 pixel screen, i reckon Tetris was better suited. Or to be more precise: horizontal Tetris. The added benefit of tetris is that it doesn’t need a high frame rate. And honestly, seeing such a cute little Tetris game on a business card, brings a smile to most people’s faces. :)
