I want to commend you on the level of details and the links to videos! Reading the article was a pleasure. The only question I had at the end (most likely left off on purpose) was the final cost of the two board solution. I assumed the dual board approach was for size/compactness and to isolate power from controls, correct?
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.
