WiFi ESP8266-12-E Serial TTL Module

Description

WiFi ESP8266-12-E Serial TTL Module 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. 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. Tile tolerates a voltage of 3.3 V. Therefore, you must choose Arduino operating on voltage 3.3 V or use a converter. Specifications: Supply voltage: 3.3 V Current consumption at rest: approx. 10 mA Chip: ESP8266 Flash memory: 4 MB Standard: wi-fi 802.11 b/g/n Operates in the 2.4 GHz frequency Supports WPA / WPA2 protections Can work in AP mode (Access Point), STA (standalone) and AP+STA Supports AT commands Communication: UART (Rx, Tx) The default UART speed: 115200 bps Mounting SMD or THT Pitch of leads: 2 mm Hole diameter: 0.9 mm Has 16 pitch leads 2 mm 11 x GPIO – digital outputs/inputs 1 x ADC input – analog-to-digital converter Equipped with communication interfaces: SPI, UART, SDIO Software support Lua Tile sizes: 24 x 16 mm Useful links System documentation ESP8266 The Wiki-page ESP8266 Example of connection of ESP-12 Sample Arduino program Comparison of ESP modules The ESP8266 community forum
