Particle Photon with Headers

Good things come in small packages as they say.In this case the tool is small enough to fit anywhere but smart enough to perform most activities.

A Photon checks into a hotel. The bellhop asks, “Can I help you with your luggage?” It replies, “I don’t have any.  I’m travelling light.”

The Photon is a $19 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 our web or local IDE, deploy it over the air, and build your web and mobile apps with ParticleJS and our Mobile SDK.
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.

This is the Photon with breadboard headers connected.
