They are usually composed of a main microcontroller and an additional connectivity (eg. ESP8266 for Wifi, ENC28J60 for Ethernet) or they are complete SOC including both the processing unit and the connectivity modems in one single package. Regardless of their form or shape, these devices open new applications for…
