Octopart Pocket Electronics Reference PCB

Ever wished for a simple way to read resistor color codes? Need an at-a-glance reference for common surface mount footprints? Then check out our crowdfunding campaign for the Octopart Pocket Electronics Reference PCB.

This resistor color code chart is compact and easy to read. We liked the simplicity of Bret Victor's Resistor Decoder - our chart also reads left to right. When the last color has a "tail" you simply add the decimal point it indicates.

On the flipside are footprints for common SMT components. Can't remember how small a 0201 capacitor is? We got you covered.

We're using an 8-color silkscreen process making what we think is the most colorful PCB ever. The cards are the same size and thickness of a credit card so they'll fit great in your wallet and the durable printed circuit board material will last a long time.

The cards are $9 each (shipping included). We're also offering an uncut 17"x22" panel of 43 cards for $400 (shipping included). Think of it as PCB art. We're getting one for the office!
