WiFi ESP8266-12-F Serial TTL وحدة

WiFi ESP8266-12-F Serial TTL Module

The WiFi ESP8266-12-F Module is a compact, high-performance wireless solution based on the ESP8266 chip, designed for embedded applications requiring reliable WiFi connectivity. Developed by Ai-thinker Team, this module integrates a low-power 32-bit MCU, a complete TCP/IP protocol stack, and advanced RF components, making it ideal for space- and power-constrained designs. With support for 802.11 b/g/n protocols, the ESP-12F offers seamless wireless communication, while its small form factor (ZKEEP0Z x ZKEEP1Z x ZKEEP2Z) and ultra-low power consumption (deep sleep mode <10uA) make it perfect for battery-operated devices. It delivers excellent RF performance, including +20dBm output power in 802.11b mode and sensitivity up to -98dBm, ensuring robust connectivity even in challenging environments.

The ESP8266-12-F can operate as a standalone application or offload WiFi networking functions from another processor, providing flexibility for a wide range of projects. It also supports over-the-air (OTA) firmware upgrades and features a Smart Link Function for easy setup with Android and iOS devices. Whether you’re building IoT devices, smart home systems, or wireless sensors, the ESP-12F offers the performance, versatility, and ease of use you need.

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 (ZKEEP18Z).

VCC

The Power – ZKEEP19Z.
