Another feature I like to look for when selecting a controller is pin compatibility in the family so that if feature creep requires moving to a bigger part from the same vendor, the board doesn't need to be re-layed out.
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.
