Description
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.
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
Connecting
The module has 22 leads, pitch of 2 mm.
| PIN | DESCRIPTION |
|---|---|
| TxD | The transmitter of the serial interface UART. |
| RxD | The receiver of the serial interface UART. |
| GPIO x | Lead GPIO (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. |

Power down – indication of low state causes a transition to sleep mode.To update, you need to indicate a high status (3.3 V). |
| VCC | The Power – 3.3 V. |
The product is compatible with ArduinoInstruction of connecting the module with Arduino basing on the module ESP-01. Tile tolerates a voltage of 3.3 V. Therefore, you must choose Arduino operating on voltage 3.3 V or use a converter. |
