Photon
The Photon is a $19 tiny Wi-Fi IoT device 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 board itself uses a Cypress 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. 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 SDKs. All Particle Hardware is designed from the ground up to work with the Device Cloud. The Device Cloud is a powerful set of tools and infrastructure to build, connect, and manage your IoT fleet. Access to the Device Cloud includes: Device Cloud FREE for first 100 devices (learn more) Device Cloud Features: - Device Management - Over the Air Firmware Updates - Fully Managed Connectivity - Developer Tools - Integrations Specs: Particle P0 Wi-Fi module Cypress BCM43362 Wi-Fi chip STM32F205 120Mhz ARM Cortex M3 1MB flash, 128KB RAM 802.11b/g/n Soft AP setup FCC/CE/IC certified Full specs here Does not ship with breadboard or USB cable. This board can ship with or without headers. Photons with headers are great for using with breadboards; Photons without headers are best for surface mounting and special applications.
