Particle Photon Development Board
Particle’s Photon is a tiny Wi-Fi development kit for creating connected projects and products for the Internet of Things (IoT). It is easy to use, powerful and connected to the cloud. The particle combines a powerful ARM Cortex M3 microcontroller with a Broadcom Wi-Fi chip in a tiny thumbnail-size module called the P0 (P-Zero).
To get you started quickly, Particle adds a rock solid 3.3VDC SMPS power supply, RF and user interface components to the P0 on a small single-sided PCB called Photon. The design is open source, so when you are ready to integrate the Photon into your product, you can.
