The ESP-12S module is a small module based on the ESP8266 chip, which has the ability to connect to the Internet and LAN networks through Wi-Fi. ESP8266 is actually a SoC with a 32-bit architecture, which, in addition to the features found in other microcontrollers, has hardware units to support all IEEE802.11, TCP/IP and P2P protocols, which made the modules ESP8266 is the core of many Internet of Things and network projects. ESP series modules are all based on the ESP8266 chip, which differ only in features and interface. The 12S version of the ESP8622 module has a PCB antenna and it is possible to connect an external antenna, it also has anti-jamming ability.
