It’s a new $4 microcontroller that’s smaller than the average Pi, features a custom chip powerful enough to be used in machine learning projects (according to The Raspberry Pi Foundation), and is on sale now.
The Raspberry Pi takes care of heavyweight computation, network access, and storage, while the microcontroller handles analogue input and low-latency I/O and, sometimes, provides a very low-power standby mode.Those specs might go in one ear and out the other, but the best way to illustrate the potential for a new Raspberry Pi product is to see it used in something cool
