R5 seems the same as A5, now with error checking and the peripheral port - otherwise not so new
R7 seems the same as A9, now with ECC, peripheral port and low latency SRAM capability

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.
