You can't have any development board without some sort of prototyping area, the SparkFun Photon ProtoShield takes care of this. This ProtoShield mates easily with your Photon module and provides a small soldering area and separated power and I2C hook-ups. With the SparkFun Photon ProtoShield you have the control over what kind of project you design for your Photon.
The Particle Photon is a tiny WiFi development kit for creating connected projects and products. Sporting a 120MHz ARM Cortex M3 and built-in WiFi, the Photon is not only powerful, but easy to use. The small form factor is ideal for IoT projects with cloud-connectivity.
Note: Not only can this shield operate with the Photon, it can also be used with the Particle Core! We understand that there are a ton of you out there who still haven't been able to get your hands on a Photon yet and would like to start playing with this shield now. If that person is you we hope we have obliged!
