3 The core processorESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU ina small package with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supportsRTOS, and integrates Wi-Fi MAC/BB/RF/ ESP-12F WiFi module supports the standard 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 esp8266 is a high-performance wireless SOC that offers maximum utility at the lowestcost and unlimited possibilities for embedding WiFi functionality into other esp8266 is a complete and self-contained WiFi network solution that can operateindependently or as a slave running on other host MCUs.
4 The esp8266 is capable of bootingdirectly from an external flash memory when it is powered by an application and is the onlyapplication processor in the device. The built-in cache helps improve system performance andreduce memory another case, the esp8266 is responsible for wireless Internet access. When it comes tothe task of the WiFi adapter, it can be added to any micro controller-based design. The connectionis simple and easy, just by SPI / SDIO interface or I2C / UART port. Just esp8266 's powerful on-chip processing and storage capabilities allow it to integratesensors and other application-specific devices through the GPIO port, minimizing systemresources during minimal up-front development and WIFI MODULE V1 Copyright 2018 Shenzhen Ai-Thinker Technology Co.
