ESP-12F WiFi module is a security technology developed by Letter to the module integrated core processor ESP8266 smaller package size tensilica L106 industry-leading ultra low power 32-bit MCU micro, with the 16 compact mode, Clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antenna.
The module supports standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack. Users can use the modules for an existing device to add 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.

When it comes to low cost micocontrollers you usually think of Arduino. But now with the Esp8266 you have a faster microcontroller with more memory and WiFi for less money. Combine that with Elecrows low cost PCB manufacturing and you have custom IOT devices to fill all of your needs. Get the ESP board definitions to allow you to program them with the familiar Arduino IDE and even use the same programs. The 12F is my goto for most prjects and I highly recommend it.
