I've discovered the limitations of the Arduino Leonard architecture. I like the Leonardo for my own boards because it doesn't require a second MCU for the USB interface, but it doesn't have enough left over FLASH.
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.
