Hi!

I bring to your attention the third version keychain for PCBWay. To better understand how they differ from each other, I took a photo with inscriptions.

All projects at first glance are very similar, but in fact there are differences in different topology and silkscreen printing. I recommend that you order all three versions and choose the one you like the most not by photo, but in real life. Each of them is amazing!

The sizes of the printed circuit board projects are very modest, only 29x25mm, and for just $ 5 you can order at least 10 pieces.

You do not need to buy any components, there are no LEDs and batteries. Only the printed circuit board.
