Description

The ESP-12S WIFI module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack. Users can use this module to add networking capabilities to existing devices or to build separate network controllers. The ESP8266 is a high-performance wireless SOC that offers maximum utility at the lowest cost and unlimited possibilities for embedding WIFI functionality into other systems.

The ESP8266 is a complete and self-contained WIFI network solution that can operate independently or as a slave running on other host MCUs. The ESP8266 is capable of booting directly from an external flash memory when it is powered by an application and is the only application processor in the device. The built-in cache helps improve system performance and reduce memory requirements. In another case, the ESP8266 is responsible for wireless Internet access. When it comes to the task of the WIFI adapter, it can be added to any micro controller-based design. The connection is simple and easy, just by SPI / SDIO interface or I2C / UART port. Just fine. The ESP8266’s powerful on-chip processing and storage capabilities allow it to integrate sensors and other application-specific devices through the GPIO port, minimizing system resources during minimal up-front development and operation.
