ESP8266 ESP-07 ESP-07S Serial WiFi Wireless Module

ESP8266 ESP-07 / ESP-07S Serial WiFi Wireless Control Module

Take your IoT and embedded electronics projects to the next level with the ESP8266 Serial WiFi Wireless Module — available in both the ESP-07 and ESP-07S variants. Compact, low-power, and incredibly versatile, this module is a go-to choice for hobbyists, makers, and engineers who want reliable wireless connectivity in their builds.

ESP-07 vs ESP-07S — What's the Difference?

• ESP-07: Features a built-in ceramic antenna and an external IPX antenna connector for extended range flexibility.
• ESP-07S: Ships without a ceramic antenna and uses an external IPX antenna connector — ideal when you need a more compact footprint or want to attach your own antenna.

Key Features

• WiFi Standard: IEEE 802.11 b/g/n — 2.4GHz band
• Operating Modes: Station (STA), Access Point (AP), and Station + AP combined
• Serial Interface: UART communication for easy integration with microcontrollers (e.g. Arduino, Raspberry Pi)
• Low Power Consumption: Ultra-efficient deep-sleep mode extends battery-powered project life
• Onboard Processing: Integrated Tensilica L106 32-bit RISC processor — runs standalone without an external MCU
• GPIO Pins: Multiple I/O pins for sensors, relays, LEDs, and more
• Flash Memory: Onboard flash for storing firmware and project code
• AT Command Support: Compatible with standard AT command firmware for quick prototyping
• Shielded Enclosure: Metal shield reduces interference for more stable connectivity

Ideal Applications

• Smart home automation and control systems
• Remote sensor data logging (temperature, humidity, motion)
• WiFi-enabled robotics and RC projects
• IoT prototyping and product development
• Wireless serial bridges and relay controllers

What's in the Box

• 1 × ESP8266 WiFi Module (ESP-07 or ESP-07S — select your variant)

Frequently Asked Questions

Q: What is the difference between the ESP8266 ESP-07 and ESP-07S WiFi modules?

A: The ESP-07 includes an onboard ceramic antenna as well as an external IPX antenna connector, giving you flexible range options. The ESP-07S omits the ceramic antenna and uses only an external IPX connector — making it slightly more compact and allowing you to attach a dedicated external antenna for specialized applications.

Q: Can the ESP8266 ESP-07 module work without an external microcontroller?

A: Yes! The ESP8266 features an integrated 32-bit processor and onboard flash memory, allowing it to run standalone firmware (such as MicroPython, NodeMCU Lua, or custom AT firmware) without requiring an external microcontroller like an Arduino.

Q: What communication interface does the ESP8266 ESP-07 use?

A: The ESP8266 ESP-07 communicates via a UART serial interface using TX/RX pins. It supports standard AT commands out of the box, making it straightforward to connect to Arduino, STM32, Raspberry Pi, or other microcontrollers for WiFi-enabled projects.

Q: What voltage does the ESP8266 ESP-07 module operate at?

A: The ESP8266 module operates at 3.3V. Ensure you use a 3.3V power supply or a voltage regulator when interfacing with 5V systems to avoid damaging the module.
