It's like Circuit Playground for your wallet! Designed by Star Simpson, MIT Engineer!

This handy, credit-card sized PCB is the perfect accessory for the amateur electrical engineer. On one side it has a beautiful eight-color silk screened resistor chart to help you identify resistors by their color (and finally beat Mho's Resistance) and on the other there's a comprehensive SMT reference with to-scale footprints for common SMT parts.

The best part of this PCB is how easy and fast it is to use. The colors are bright and the card's clear and intuitive. And the back's handy for anyone who has grown beyond through-hole soldering and is ready to take on surface mount.
