I think maybe we need to write a guide to all of these so people can see what is out there and compare them. The MBed is a nice piece of hardware, I've seen it used many times. There's also the teensy, digispark, femtoduino, etc.
That's a pretty neat trick, fitting 37 I/Os into a 28-pin DIP, two pins of which are used for power and GND. Speaking of which, I wonder how much ground bounce you get if you switch multiple outputs simultaneously?
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
