The ESP-12S WiFi module was developed by B&T Technology. The core processor of the module ESP8266integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package with16-bit reduced mode. The main frequency supports 80 MHz and 160 MHz, supports RTOS, and integratesWi-Fi MAC / BB / RF / PA / LNA. The ESP-12S WiFi module supports the standard IEEE802.11 b/g/n protocol, a completeTCP/IP protocol stack. Users can use this module to add networking capabilities to existingdevices or to build separate network controllers. The ESP8266 is a high-performance wireless SOC that offers maximum utility at the lowestcost and unlimited possibilities for embedding WiFi functionality into other systems.
