@rickmerritt & @richQ: those are actual dev boards (snapdragons, tegra-based etc.) - physical real devices on you can test other things than just apps. And generally what is understood as a fragmentation on Android is not just software related but hardware has lots of things to do with it as well.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
