The ESP8266 NodeMCU V10 ESP-12E WiFi module is the latest version of this popular module and can be used as a WiFi enabled replacement for an Arduino in many applications. Variants of it like the ESP-07 with antenna connector often have the same pin assignment and how it is prepared with the help of 5x 10kΩ resistors for normal operation as well as the flash mode.

Pin Di Arduino
ESP12E is a family of ESP8266.
Esp 12. These resistors control the mode of operation at reset. In this drawing you can see the ESP-12 chip by the way. The plain vanilla ESP-12 has only 16 pins 8 on each side.
The module can operate with the same language Arduino board uses. A Breadboard starting from a few dollars on ebay for example. With these resistors installed the module will operate in normal mode after reset.
The ESP-12E adds 6 more on the bottom edge for 22 total. There are different versions of this chip equipped with a flash from 512KB to 4 MB. Original ESP-12 without adapter board.
Starting with the ESP-12 and the Arduino tools. CH_PD aka EN is a signal that can be used to power down the unit in an application that wants to do this to save power. The new four-layer board design.
Yes The ESP-12 is pretty outdated still a few offers are left on the market. The PINs will help to communicate through Arduino programming. ESP8266 NodeMcu is a popular and widely used development board based on the ESP-12E WiFi Module that combines elements of easy programming with Arduino IDE CC and WiFi capability.
Breakthrough design there are new breakthroughs based on ESP-12E. ESP-12F Module from ebay for example around 231USD. Be carefull with buying or prefer ESP-12EF types.
So Arduino IDE uses Generic ESP8266 for ESP12E. The version of ESP8266 used in this project is the ESP-12 the newer fancier model with RF shielding a questionable FCC logo and every single one of the GPIOs exposed on castellated connectors. The ESP-12 has a 2mm pitch which means you cannot access all the pins on a breadboard or a perforated dot matrix directly which have a 254mm pitch distance between adjacent pins.
The ESP-201 is good for solder-free prototyping on a bread board and allows you to access almost all pins of the ESP8266 chip. In this video we will take a look at 3 different ways of programming an ESP8266-12 ModuleThis is a re-upload with fixed wiring diagrams-----. The one that we are using in the tutorial is the ESP8266-12We already covered ESP8266-01 in our previous articleHowever all the ESP modules have only one type of ESP processor what differs is only the type of breakout bard used.
There are many types of ESP8266 module available ranging from ESP8266-01 to ESP8266-12. The ESP-12F has the same pinout as the E but an improved antenna. Esp-12 Pic Pinout ListPic FCC.
The new revision antenna RF performance optimization communication distance is increased by 30 -50 compared to ESP-12E. Core processor ESP8266 in smaller. Semi-hole chip technology the whole IO leads with metal shielding shell Passed FCC CE RoHS certification Built-board PCB antenna 4M bytes SPI.
Here is the list. The Hardware needed is the same as in my the first test plus a breadboard. During the use of ESP12E there wont be any library.
The ESP-12 might be interesting if you have periphery based on SPI or I2C bus or if you just many GPIO pins and you are not afraid of a bit of soldering. I just ignore it. Preambles ESP-12E WiFi module is developed by Ai-thinker Team.
An optional ESP-12 adapter like this ones from ebay. An USB to serial TTL UART Module like CP2102 from ebay for exemple. You could use a Xbee adapter board but theres an easier way out.
The resistors can be overpowered to disable the module or reboot in a. A few resistors have to be added to the ESP-12E module for proper operation. Take a small length of single strand cable or multi strand cable and get a spider web breakout like this.
To upload the device Arduino requires the UART communication pins RX and TX only. It is the ancestor of the nowadays ESP-12E and ESP-12F just some GPIO-Pins missing. 124USDA 33V Power supply like MB102 from ebay.
