Product description: Module WiFi ESP-12E ESP8266

Wi-fi module based on the ESP8266 chip. Works in standard wi-fi 802.11 b/g/n at 2.4 GHz. Equipped with 22 leads - pitch 2 mm, of which 11 is GPIO, 1 ADC and SPI. Has a built-in LED and a PCB antenna. The plate size 24 x 16 mm.

Compared to the previous version of ESP-12, ESP-12E has additional GPIO pins and SPI interface available on the narrower edge of the module in the form of soldering pads.

 

In our offer, you will also find an adapter that allows you to attach the system into the breadboard.

Features of the module ESP-12E

Features that distinguish the ESP 12-E module on the background of the whole family of ESP-XX:

  • Has 16 pins:
    • 11 x GPIO - digital outputs/inputs
    • 1 x ADC input - analog-to-digital converter
    • 1 x SPI interface
    • 1 x I2C interface
    • 2 x UART (TX, RX) - for communicating, for example with Arduino
  • Mounting: SMD / THT:
    • Holes diameter: 0.9 mm
    • Pitch of leads: 2 mm
  • The default UART communication speed: 115200 bps
  • Equipped with built-in PCB antenna
  • Module shielded
  • Dimensions: 24 x 16 mm

 

Connection with the module of WiFi ESP-12E ESP8266

The module has 22 pins,pitch of 2 mm.

Pin Description
TxD The transmitter of the serial interface UART.
RxD The receiver of the serial interface UART.
GPIO x GPIO pin (digital output/ input) with a serial number.
GPIO 0 GPIO with special function:

To update, you need to indicate the low status (connect to GND).

GPIO 15

GPIO No. 15 with a special function:

In normal and programming mode should indicate the low status (conect to GND).

ADC Input of analog-to-digital converter.
REST The system reset.

EN

(CH_PD)

Power down - indication of low status causes a transition to sleep mode.

To update, you need to indicate a high status (3.3 V).

VCC The power supply is 3.3 V.

 

The product is compatible with Arduino

Instruction of connecting the module with Arduino basing on the module ESP-01, you can find on the blog Majsterkowo and in guide prepared by us.

 

The board tolerates a voltage of 3.3 V. Therefore, you must choose Arduino operating with the voltage of 3.3 V or use a converter.
