ESP-07S ESP8266 Serial WIFI Module

Description

Product Overview

The ESP-07S ESP8266 Serial WiFi Module is a professional-grade, compact wireless communication module designed for IoT applications requiring robust connectivity in a space-constrained form factor. Developed by Ai-Thinker, a leading manufacturer of IoT communication solutions, this module represents an optimized evolution of the ESP-07 platform, offering enhanced performance and simplified integration .

Built around the powerful ESP8266EX chip from Espressif Systems, the ESP-07S integrates a Tensilica L106 32-bit microcontroller with a complete Wi-Fi solution, including a TCP/IP protocol stack, onboard PA, LNA, and matching network . This allows the module to function either as a standalone application processor or as a Wi-Fi adapter for other microcontrollers, providing exceptional flexibility for your design needs .

The ESP-07S features a U.FL/IPEX connector for external antenna attachment, allowing you to overcome signal attenuation issues common when modules are mounted inside metal enclosures or when extended range is required . Unlike its predecessor (ESP-07), the ESP-07S uses a PCB trace antenna by default, with the option to connect an external antenna via the U.FL connector, offering a more streamlined and cost-effective design .

With its compact SMD-16 package (16mm × 17mm × 3mm) and industrial temperature rating (-40°C to +125°C), the ESP-07S is designed for automated assembly and reliable operation in demanding environments . Whether you’re building smart home devices, industrial wireless sensors, or wearable electronics, the ESP-07S delivers the performance, range, and reliability your project demands.
