ESP8266 WiFi GPIO Shield for Arduino

ESP8266 WiFi GPIO Shield for Arduino -  Add Internet to your next project with an adorable, bite-sized WiFi microcontroller at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a complete WiFi front-end (both as client and access point) and TCP/IP stack with DNS support. At the same time, this chip has been very popular; it has also been tough to use. Most low-cost modules are not breadboard friendly, don't have an onboard 500mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified...UNTIL NOW!

Standard pin interface to achieve full compatibility with the pitch for Arduino Uno, Mega, and so on. (Unless the standard size for Arduino, such as Nano or Mini)
3.3V power supply using advanced chip (with the official expansion board power chip CC3000 same), so 3.3V for Arduino board provided more accurate, so ESP8266 as official cc3000 chip work as usual, there is no gap.
It leads to a WiFi module power supply/service interface to facilitate developers to extend the power supply and maintenance.
Onboard ESP8266-12 stable industrial grade serial WiFi module, using an enhanced PCB antenna, signal better.
You can quickly switch the DIP switch ESP8266-12 industrial grade WiFi stable operation mode (such as operating mode and upgrade mode) module, integrated serial chip, fast flashing the firmware.
Built-in 5V to 3.3V TTL level converter to prevent high pressure for Arduino TTL level of the WiFi module damage.
Onboard ESP8266-12 stable industrial grade WiFi module with a metal shield, immunity to interference.
Onboard ESP8266-12 standard pitch leads to a stable industrial-grade WiFi module for all interfaces, enabling developers to develop deep quickly.
Use a stackable design; it can continue accumulating above the other modules and is easy to use.
Onboard four LED displays the status of ESP8266, namely PWR, DFU, AP, STA

Scope of application: 

Remote control aircraft electrical/model/four-axis, etc
For smart devices, provide networking services
Household temperature/humidity/PM2.5 monitor, etc
Intelligent switch etc.

Frequently asked questions about ESP8266 WiFi GPIO Shield for Arduino.

Ques 1) The ESP8266 WiFi Module: What Exactly Is It?

Ans 1) With an integrated ESP8266 system on chip, the ESP8266 WiFi module is a powerful yet reasonably priced surface-mountable WiFi module (SoC). It's one of the most widely used low-cost ($4–$10.00) WiFi modules for device control over the internet.

With support for the TCP/IP communication protocol stack, WiFi security, including WAP3, and a wireless WiFi transceiver that operates in the unlicensed frequency band of 2400-2484 MHz, the module complies with IEEE 802.11 b/g/n standard. It can function as a self-sufficient programmable MCUs with an RTOS-based SDK that can run programs. It can also operate with firmware to give Wi-Fi connectivity to external host MCUs like Arduino.

ESP8266 Module Variants

The Chinese firm Espressif produced the initial ESP8266 WiFi module. Later, a different manufacturer named Ai-Thinker popularised it throughout the rest of the world. Today's market offers a variety of ESP8266 modules made by various manufacturers.

To learn the full specification of transmitters, pinout distributions, GPIOs, and other characteristics for differentiation, it is crucial to consult the datasheet for each module. Here is a list of the most popular modules offered by Ai-Thinker.

ESP-01:The WiFi serial transceiver module ESP-01's settings can be changed using AT commands. There are two variants of this module:

ESP-01S – has a 14.4 x 24.7-millimeter size, 6 GPIO pins, an ADC pin, and 1MiB flash memory.
ESP-01M – includes 16 GPIO and ADC pins, an 18 by 18-millimeter size, and 1 MiB flash memory.

ESP-07S: This module has a full WiFi front end and supports the IEEE 802.11 b/g/n protocol with a full TCP/IP protocol stack. It is a low-power 32-bit MCU clocked to support 80 MHz and 160 MHz. Its dimensions are 17 by 16 millimeters, and it contains a single UFL antenna connector, 14 GPIO pins, and 4MiB of flash memory.

ESP-12F: With a few minor variations, the ESP-12F's 24 by 16-millimeter size, PCB trace antennas, and 20 GPIO and ADC pins are comparable to those of the ESP-07S.
