Particle Photon Wi-Fi Module

Description
Particle's Photon Development Board is a powerful platform for projects that require WiFi and Internet-connectivity. Whether you're creating the next, great, IoT project, or just want an easy to use, over-the-air-programmable ARM Cortext M3 development board, the Photon is an excellent foundation.
Particle™s IoT (Internet of Things) includes a hardware development kit that provides everything you need to build a connected project. This board has combined a powerful 120Mhz ARM Cortex M3 microcontroller with a Broadcom Wi-Fi chip in a tiny thumbnail-sized module called the P˜ (P-Zero), but no antenna.
The Photon has an RGB LED and two buttons--Setup and Reset--to switch between different modes to help debug your project.
It also includes headers.
