Appendix A. Parts and Suppliers
Parts
The following tables will help you to find the parts used in this book. Where possible, I have listed product codes for a few suppliers.
There are now many electronic component suppliers that cater to the maker and electronics hobbyist. Some of the most popular are listed in Table A-1.

The other great source of components is eBay.
Searching for components can be time consuming and difficult. The Octopart component search engine can be very helpful in tracking down parts. MonkMakes, Adafruit, and SparkFun all have packs of components to get you started.
Prototyping Equipment and Kits
Many of the hardware projects in this book use jumper wires of various sorts. Male-to-female leads (to connect the Raspberry Pi general-purpose input/output [GPIO] connector to a breadboard) and male-to-male (to make connections on the breadboard) are particularly useful. Female-to-female are occasionally useful for connecting modules directly to GPIO pins. You rarely need leads longer than 3 inches (75 mm). Table A-2 lists some jumper wire and breadboard specifications, along with their suppliers.
A handy way to get started with a breadboard, jumper wires, and some basic components is to buy a starter kit, like the Electronics Starter Kit for Raspberry Pi from MonkMakes.
