1. Product overview

The ESP-12L WiFi module was developed by Ai-Thinker Technology. The core processor

ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in

a small package with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supports

RTOS, and integrates Wi-Fi MAC/BB/RF/PA/LNA.

The ESP-12L 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.
