Adafruit Particle Photon without Headers

The Photon is a $19 tiny Wi-Fi development kit designed for building and creating connected projects and products for the Internet of Things. It's easy to use, powerful, and connects seamlessly to the cloud, providing an efficient solution for digital development.

Its ecosystem, including a web and local IDE, allows you to write and deploy firmware over the air, while also providing tools like ParticleJS and a Mobile SDK for building web and mobile apps.

Equipped with a Broadcom WICED Wi-Fi chip, similar to those in products like Nest Protect and Amazon Dash, it features an STM32 ARM Cortex M3 microcontroller, ensuring superior performance and reliability.

Comparable to the Spark Core but more advanced, the WICED chipset offers faster processing speeds, SSL support, and Soft-AP mode. It can be connected via castellated pads or attached to a surface mount PCB, enhancing flexibility in design and application.
