Particle's IoT (Internet of Things) hardware development board, the Photon, provides everything you need to build a connected project. Particle has combined a powerful 120Mhz ARM Cortex M3 micro-controller with a Broadcom Wi-Fi chip in a tiny thumbnail-sized module called the PØ (P-Zero).
These specific Photons come with headers, making prototyping easy as each board can plug directly into standard breadboards and perfboards, and may also be mounted with 0.1" pitch female headers on a PCB. The Photon is not only powerful, but easy to use. The small form factor is ideal for IoT projects with cloud-connectivity. To get you started quickly, Particle has added a rock solid 3.3VDC SMPS power supply, RF and user interface components to the PØ all on a small single-sided PCB.
Your 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.
