Custom Keyboard
Hey Everyone, I am building a custom keyboard following the Caldera keyboard guide from makerworld. The one thing I am curious about is that most of my research and understanding of diodes says that they have a polarity, but the diodes that I bought from typeractive did not seem to have any identifying marks that would tell me which direction they should go. Are there diodes bi directional?

Hey there! Thanks for reaching out.
The diodes we sell are indeed polarized and need to be installed in a specific direction. They should have a small line on one end indicating the cathode. This line should match up with the line on the PCB.
If you're having trouble seeing the line on the diode itself, sometimes it helps to look at them under good lighting or with a magnifying glass.
Let me know if you have any other questions! You can reply to this message or tag me for further assistance.
