Hi David, To give an Idea of the size of the small boxes, a pound coin (euro) will just fit on the lid, the depth is about a pound coin deep. The lids flip up when opened and they are just great for smd resistors and capacitors.
I got my first set when I bought an E25 run of SMD capacitors and since then I buy them for any smd items.
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.
