The ESP8266 ESP-12E UART Wireless WIFI Shield TTL Converter (Shield WiFi ESP8266) makes it easy to connect the Arduino to WiFi networks through the ESP8266. When using it, it is no longer necessary to mount a circuit with several components and wires to interconnect an ESP8266 to the Arduino, simply attach the board to the Arduino, position the DIP switch path according to the shield operating mode and program the Arduino to connect to WiFi networks. In addition, the board can be used without the Arduino, as it has all the pin-outs of the ESP-12E available.

In the shield there is the information that it was created by a person named WangTongze and who owns the rights of it is the elecshop.ml. Initially the shield`s creator tried to raise funds for his project through Indiegogo (collective funding site), but he was unsuccessful in raising money.



- 32-bit RISC architecture

- Processor can operate at 80MHz / 160MHz

- 32MB flash memory

- 64kB for instructions

- 96kB for data

- Standard native WiFi 802.11b / g / n

- Operates in AP, Station or AP + Station mode

- It has 11 digital pins

- It has 1 analog pin with 10-bit resolution

- Digital pins except the D0 have interrupt, PWM, I2C and one wire

- Programmable through USB or WiFi (OTA)

- Compatible with Arduino IDE

- Compatible with modules and sensors used in Arduino

- Size of the Arduino Uno R3 and the pinning is compatible with Arduino Uno, Mega 2560, Leonardo and derivatives.

- Minor versions of the Arduino (Nano and Pro Mini, for example) are compatible, but connections must be made through jumpers.

- Arduino voltage (5V) is used to power the shield.

- Has AMS1117 3.3V voltage regulator, so the 5V voltage supplied by the Arduino is reduced to power the shield without the need for external power.

- It has built-in logic level converter, so the Arduino TTL level (5V) does not damage the ESP8266 that operates with TTL 3.3V level.

- It has a 4-way DIP switch that serves to change the operating modes of the board.- Available operating modes: WiFi Shield for Arduino / sending AT commands through Arduino / firmware upgrade through USB Serial external / standalone converter.

- It has indicative LEDs (PWR / DFU / AP / STA).

- Because it is in shield format, it allows other shields and modules to be inserted.

- It has the ESP-RST button to reset the ESP8266.

- The ESP8266 ADC pin is available in two forms on the board, the first on a pin with 0 to 1V reading range and the second form in the 0 to 3.3V range.
