Disclaimer: This hardware SKU will be discontinued due to lack of availability of critical components driven by the ongoing global silicon shortage crisis. For more details, visit our product discontinuation notification. It is recommended that buyers of this impacted SKU migrate to our new Supply Secure Photon 2 development board, available for purchase at volume in Q1 2023. This migration will require minimal hardware and firmware changes, as this new SKU is API compatible with both the Photon and Argon, as well as footprint compatible with the Argon. For more details, review our Supply Secure blog post. *Please note that Photon WiFi Development Boards without headers are discontinued and no longer manufactured* Buy this hardware and start building with Particle's Free Plan which includes support for up to 100 devices, cellular data, and fully-featured platform access with no time limit. The Photon is a 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. 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. If you are looking for these items to accompany your Photon, please see our Photon Kit. 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.
