unless I am missing something, 69$ for this board is on the high side. 30-40$ would have been the right price.. I would expect these guys do a better negotiation with vendors like Qualcomm, as, if some product made of these kits takeoff, those vendors would be the direct beneficiaries.
Excellent idea. There is a lot of competition in that space right now. The fact that it's and Arduino gives it a leg up as does the pre-made API.
Depending on how complete and easy to use thee APIs are, it could be a very big leg up. Trying to communicate between the processor on the board (not just to the web server) and the client web page is not as easy as it should be. Hopefully this will mitigate that difficulty.
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.
