The Particle Photon Kit includes a Photon with headers , a shiny white half-size solderless breadboard, a USB-micro cable, and a couple of extra surprises (two resistors, an LED, and a photocell) to help you start building your Internet of Things projects right away.
Your Particle Photon comes with access to the Particle Cloud, a free cloud service. The Particle Cloud has some great features for building connected projects, including over-the-air firmware updates, an easy-to-use REST API, and firmware development supported by web and local IDEs.
