ESP-07 ESP8266 Serial WIFI Module

Description

Product Overview

The ESP-07 ESP8266 Serial WiFi Module is a professional-grade wireless communication module designed for IoT applications requiring robust connectivity and flexible antenna options. Developed by Ai-Thinker, a leading manufacturer of IoT communication solutions, this module builds upon the revolutionary ESP8266 platform with enhanced features for industrial and commercial applications .

What sets the ESP-07 apart from its smaller counterpart (ESP-01) is its dual antenna capability—it features both a high-sensitivity onboard ceramic antenna and a U.FL/IPEX connector for attaching an external antenna . This design allows you to overcome signal attenuation issues common when modules are mounted inside metal enclosures or when extended range is required.

The module is based on the ESP8266EX chip from Espressif Systems, integrating a Tensilica L106 32-bit processor, Wi-Fi MAC/BB/RF/PA/LNA, and a complete TCP/IP protocol stack . It can operate either as a standalone application processor or as a Wi-Fi adapter for other microcontrollers, providing exceptional flexibility for your design needs.

With its SMD-16 package, the ESP-07 is designed for automated assembly and industrial-scale production, yet remains accessible for prototyping and custom development . Whether you’re building smart home devices, industrial wireless sensors, or wearable electronics, the ESP-07 delivers the performance, range, and reliability your project demands.

Key Features

• Dual Antenna Design: Equipped with both a high-sensitivity onboard ceramic antenna and a U.FL/IPEX connector for external antenna attachment. This provides the flexibility to use the built-in antenna for most applications or connect an external antenna for extended range and overcoming signal attenuation .

• Powerful 32-bit Processor: Built around the Tensilica L106 32-bit RISC processor running at 80 MHz (upgradable to 160 MHz), providing ample processing power for IoT applications without requiring an external microcontroller .

• Industrial Temperature Range: Rated for operation from -40°C to +125°C, making it suitable for demanding industrial environments, outdoor installations, and automotive applications .

• Complete Wi-Fi Solution: Supports 802.11 b/g/n protocols at 2.4GHz with integrated TR switch, balun, LNA, power amplifier, and matching network. Delivers up to +19.5dBm output power in 802.11b mode with excellent receiver sensitivity down to -98dBm .

• Rich Peripheral Interfaces: Provides UART, GPIO, I2C, I2S, HSPI, PWM, and 10-bit ADC interfaces, allowing connection to a wide variety of sensors, actuators, and display devices .

• Multiple Operating Modes: Supports Station (STA), Access Point (AP), and Station+AP modes, enabling devices to connect to existing networks or create their own .

• Ultra-Low Power Consumption: Features multiple sleep modes with deep sleep current as low as 10µA and standby power consumption less than 1.0mW (DTIM3) , making it ideal for battery-powered applications .

• Fast Wake-Up: Can wake from sleep, connect, and transmit data in less than 2ms, enabling efficient power management for intermittent data transmission .

• Smart Configuration Support: Compatible with Smart Config and AirKiss one-click network configuration technologies, simplifying device onboarding .

• SMD Package for Automated Assembly: The 16-pin SMD package is designed for automated surface-mount assembly, making it suitable for large-scale production while remaining accessible for hand soldering .
