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.
|
Compared tothe 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 findan adapterthat 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
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. |
|
EN (CH_PD) |
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 Arduino Instruction of connecting the module with Arduino basing on the module ESP-01, you can findon the blog Majsterkowoand in guideprepared by us.
Tile tolerates a voltage of 3.3 V. Therefore, you must chooseArduino operating on voltage 3.3 Vor usea converter. |
