Summary

In this chapter, we looked at the high-level design of IoT devices. We looked at different types of hardware that IoT devices can be built on—SBCs, microcontrollers, and FPGAs. We considered the various ways these devices can connect to the internet, including wired and wireless connections, and we weighed some trade-offs associated with each.

We also took into consideration some of the protocol choices that IoT devices can use and reiterated the importance of security.
