This ESP8266 IC based ESP-12F variant is a WiFi module which can give your Arduino or other electronic projects WiFi capabilities and can even be used on its own by reprogramming the ESP8266 MCU!
Overview
The ESP8266 is a highly integrated chip designed for the needs of a new connected world and is the go to choice for IOT. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.
There is an almost limitless fountain of information available for the ESP8266, all of which has been provided by amazing community support.
Additionally, the ESP8266 Basics Wiki covers all of the key differences between the various ESP8266 versions available, so be sure to take a look at this and see which is the ideal fit for your projects.
The ESP-12E and ESP-12F today are the all days ESP. The only difference is the layout of the PCB antenna. The ESP12F has an optimized antenna, that’s the only difference.
Compared to the ESP-07S and the older ESP-07 and ESP-12 the ESP-12E has more GPIO pins lead to the outside.
Beware! These additional GPIOs are made for SPI connection and using SD-cards. Use GPIO10 with care, do not use GPIO9. Test your circuit thoroughly. Keep in Mind GPIO10 will switch to “high” for some seconds on bootup. Do not connect a switch or sensor to this pin that forces it to “low”.
