1. ESP-12E is a Wi-Fi module developed by Essence Technology. The core processor ESP8266 of this module integrates Tensilica L106 ultra-low power consumption 32-bit Mini MCU in a smaller size package with 16-bit streamlined mode. The frequency supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi-Fi //RF/PA/LNA. 2. The ESP-12E Wi-Fi module supports the standard IEEE802.11 b/g protocol and the complete IP protocol stack. Users can use this module to add networking capabilities to existing devices or build network controllers. 3. ESP8266 is a high-performance wireless SoC that provides maximum practicality at the lowest cost and unlimited possibilities for embedding wifi functions into other systems. 4. ESP8266 has complete and self-contained Wi-Fi network functions, which can be used independently or run as a slave on other host MCUs. When ESP8266 is used independently, it can be started directly from the external flash. The built-in cache memory helps improve system performance and optimizes the storage system. In another case, ESP8266 can be used as a WiFi adapter through the SPI/SDIO interface or UART interface and can be applied to any Minicontroller-based design. 5. The powerful on-chip processing and storage capabilities of ESP8266 enable it to integrate sensors and other application-specific devices through the GPI0 port, greatly reducing the cost of early development.
