NOTE : The Pictures above for the Green and Gloss Black, the Pads are SILVER, not Gold-ish as they appear in the photos, my camera setup just isn't very good.
This is a novelty PCB ruler with some keyboard-specific additions. It has footprints for the most popular switches, as well as a "Cap" rule that allows you to measure the size of a keycap. It also features a diode bender to allow you to bend diodes to the same size.
Furthermore the ruler CAN be fully assembled using SMD components to get a functional macro pad, you can find the BOM here - LINK
Note: If you just solder on the Mini USB port and 470 Ohm PWR LED resistor, you can use the PWR led contacts to test LEDs.
There are 3 colors available, please refer below for more information on each option.
Green - Green PCB and Silver (HASL) Pads
Glossy Black - Glossy Black PCB and Silver (HASL) Pads
