The Photon is an open source, inexpensive, programmable, WiFi enabled module for building connected projects and prototypes Powered by an ARM Cortex M microcontroller and a Broadcom WiFi chip, the Photon is just as happy plugged into a hobbyist s breadboard as it is into a product rolling off of an assembly line While the Photon and its accompanying cloud platform is designed as a ready to go foundation for product developers and manufacturers, it s great for Maker projects, as you ll see in this book You ll learn how to get started with the free development tools, deploy your sketches over WiFi, and build electronic projects that take advantage of the Photon s processing power, cloud platform, and input output pins What s , the Photon is backward compatible with its predecessor, the Spark Core
