1. Preambles
ESP-12F WiFi module is developed by AI-Thinker Co.,Ltd, core processor ESP8266 in smaller sizes of the module
encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode,
clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antennas.
The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the
add modules to an existing device networking, or building a separate network controller.
ESP8266 is high integration wireless SOCs, designed for space and power constrained mobile platform designers.
It provides unsurpassed ability to embed Wi-Fi capabilities within other systems, or to function as a standalone
application, with the lowest cost, and minimal space requirement.
ESP8266EX offers a complete and self-contained Wi-Fi networking solution; it can be used to host the application
or to offload Wi-Fi networking functions from another application processor.
When ESP8266EX hosts the application, it boots up directly from an external flash. In has integrated cache to
improve the performance of the system in such applications.
Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any micro controllerbased design
with simple connectivity (SPI/SDIO or I2C/UART interface).
ESP8266EX is among the most integrated WiFi chip in the industry; it integrates the antenna switches, RF balun,
power amplifier, low noise receive amplifier, filters, power management modules, it requires minimal external circuitry,
and the entire solution, including front-end module, is designed to occupy minimal PCB area.
ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor, with on-chip
SRAM, besides the Wi-Fi functionalities. ESP8266EX is often integrated with external sensors and other application
specific devices through its GPIOs; codes for such applications are provided in examples in the SDK.
