UNO R3 Mega 3.3V ESP8266 WIFI Shield Development Board ESP-12E Module For Arduino

Product Description of Serial WiFi Expansion Board

1. Product Parameters

● Name: Serial WiFi Expansion Board

● Model: ESP-12E

● Power Chip: 3.3V Power Chip

● Size: 685318.2mm

● Weight: Approximately 22.3g

2. Usage Instructions

● Convenient Startup: One - click to enter the flashing mode, no additional wiring required

● Compatible Design: Mini pin spacing is compatible with Uno, Mega, Nano, etc. (except for non - standard sizes)

● Power Adaptation: 3.3V power chip (same as the official CC3000 expansion board), enabling the ESP8266 to work stably; Power/maintenance interfaces of the WiFi module are led out for easy power supply and maintenance

● Core Module: Equipped with the ESP8266-12E industrial - grade stable serial WiFi module, paired with an enhanced PCB antenna for strong signals

● Mode Switching: A dial switch for quickly switching operating modes (such as built - in/upgrade mode), integrated chip for fast firmware writing

● Level Protection: Built - in 5V to 3.3V level converter to avoid high - voltage damage to the WiFi module (generally not available in ordinary modules)

● Anti - interference: The ESP8266-12E module has a metal shield cover, with strong anti - interference ability

● Rich Interfaces: All interfaces are led out with standard spacing, supporting in - depth development

● Flexible Expansion: Double - layer stacking design, allowing for connecting other modules continuously

● Status Visibility: 4 LEDs display the status of ESP8266 (PWR, DFU, JAP, STA), with operating modes intuitive

3. Product Applications

● Remote Control: Networked control of electrical appliances/models/four - axis aircraft, etc.

● Smart Upgrade: Adding network functions to non - smart devices

● Environmental Monitoring: Home - use temperature/humidity/PM2.5 displays

● Smart Control: Smart switch scenarios
