ESP-12E WiFi Module Espressif ESP8266 MCU

3.95 

Module based on the ESP8266 SoC, ideal for being soldered directly into IoT projects, exposes all the chip pins, takes up little space and has an even smaller price.

Connecting your projects to the internet via WiFi will no longer be a problem with the help of the ESP-12E module. It is based on the ESP8266 SoC (System on Chip), a highly integrated chip designed for the needs of a connected world. This module or SoM is the core of the NodeMCU and Wemos D1 Mini boards. The ESP8266 integrates a powerful processor with 32-bit architecture (more powerful than the Arduino Due) and WiFi connectivity. It offers a complete and self-contained WiFi Networking solution, it can work as an application host or offload the WiFi Networking load from another processor.

The ESP-12E module comes pre-loaded with AT firmware, which allows connecting an Arduino to WiFi using AT commands. It is possible to change the firmware (flash) allowing the module to work independently or as an SDK (without an Arduino) and use all its capacity as a 32-bit 80Mhz microcontroller. To flash the chip it is necessary to use a USB to serial TTL converter module such as the CP2102 module.

The ESP-12E module works at 3.3V for power and GPIO so it should NOT be powered with 5V. It is recommended to place a 100uF capacitor in parallel with the power supply to filter current spikes. It has power and communication indicator LEDs. The input/output pins (GPIO) work at 3.3V so for connection to 5V systems it is necessary to use level converters such as: 3.3-5V 4CH Level Converter or 8CH Bidirectional Level Converter – TXS0108E.

The ESP8266 SoC (System On a Chip) from Espressif Systems is a chip specially designed for the needs of a connected world, integrating a powerful microcontroller with 32-bit architecture (more powerful than the Arduino Due) and Wi-Fi connectivity. The ESP-12E SoM (System on Module) manufactured by Ai-Thinker integrates the ESP8266 SoC, FLASH memory, oscillator crystal and WiFi antenna on a PCB in a single module.

The ESP8266 platform allows the development of applications in different languages such as: Arduino, Lua, MicroPython, C/C++, Scratch. By working within the Arduino environment we can use a well-known programming language and make use of an easy-to-use IDE, as well as make use of all the information about projects and libraries available on the Internet. The Arduino user community is very active and supports platforms such as the ESP8266. Among the main development boards or modules based on the ESP8266 we have: ESP-01, ESP-12E, Wemos D1 mini and NodeMCU v2.
