ESP-07 ESP8266 WiFi Module

ESP-07 ESP8266 WiFi Module

The ESP-07 is a compact ESP8266-based WiFi module that enables any microcontroller to connect to 802.11b/g/n wireless networks. Pre-flashed with AT firmware, it is controlled via simple serial AT commands at 115200 baud. It features both an onboard ceramic antenna and a uFL connector for an external antenna.

Key Features

• ESP8266 WiFi SoC — 802.11b/g/n
• AT command firmware pre-flashed
• Onboard ceramic antenna + uFL external antenna connector
• Operating voltage: 3.3V only
• Serial UART interface (115200 baud default)
• Supports TCP/UDP, HTTP, MQTT protocols

Important Note

This module operates at 3.3V only. Use level shifters when interfacing with 5V microcontrollers such as Arduino Uno.

Applications

• IoT sensor nodes and data loggers
• Arduino and ESP32 WiFi connectivity
• Home automation and smart devices
• Remote monitoring systems
