The Photon is a tiny Wi-Fi development kit for creating connected projects and products for the Internet of Things. It's easy to use, it's powerful, and it's connected to the cloud.
The tools that make up the Photon's ecosystem (and come along with the board) are designed to let you build and create whether you're an embedded engineer, web developer, Arduino enthusiast or IoT entrepreneur. You'll be able to write your firmware in web or local IDE, deploy it over the air, and build your web and mobile apps with ParticleJS and Mobile SDKs.
The board itself uses a Broadcom wi-fi chip (one that can be found in Nest Protect, LIFX, and Amazon Dash) alongside a powerful STM32 ARM Cortex M3 microcontroller. It's like the Spark Core. But better.
Does not ship with breadboard or USB cable. This board ship with headers. Photons with headers are great for using with breadboards; Photons without headers are best for surface mounting and special applications.
