PS For others just coming in, my article originally said $5 a board for the prototype (unpopulated) PCBs -- I made a mistake -- it should be $25 -- and I just made that change in the article -- so UncleRemus wasn't imagining things (grin)
@UncleRemus: Sorry -- this was my bad -- I was interviewing John over the phone -- he said "$25" but I heard "$5" and that's what I wrote down.
I just touched base with John again, he says that the price was $25 each for a 1.5" x 4", quantity = 4, and a 2-week turnaround time.
But still and all, I think $25 for a hobbyist prototype board of this level of sophistication is a REALLY good deal. I don;t want to think what I've ended up paying other board vendors in the past...
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.
