ESP-WROOM-02-N2 WiFi模块产品概述

一、产品定位与核心特性

ESP-WROOM-02-N2是乐鑫(ESPRESSIF)推出的集成式WiFi射频收发器模块,以自研ESP8266EX为核心芯片,支持IEEE 802.11b/g/n协议,工作在2.4GHz~2.5GHz全球通用WiFi频段。采用SMD-18P表面贴装封装,专为物联网(IoT)、智能家居、工业监测等场景设计,兼顾性能稳定、集成度高、成本可控三大核心优势。

二、核心硬件参数

模块的关键硬件参数覆盖射频性能、供电、环境适应性等维度,具体如下:

  • 射频核心:搭载ESP8266EX SoC,集成WiFi基带与射频前端,无需外接额外射频芯片,简化系统设计;
  • 天线形式:板载PCB天线,无需外接天线即可实现稳定无线连接,节省PCB空间;
  • 发射功率:20dBm,可提供较好的信号覆盖范围(室内多房间、小型厂区等中距离场景适用);
  • 供电范围:2.7V~3.6V,兼容3.3V主流电源及锂电池(3.7V锂电池经稳压后可直接供电);
  • 电流消耗:接收模式5056mA,发送模式120170mA(典型值,随数据速率/调制方式略有变化);
  • 接收灵敏度:多组典型值(-98dBm、-93dBm、-91dBm等),其中-98dBm为低速率模式下的高灵敏度,抗干扰能力强;
  • 工作温度:-40℃~+85℃,达到工业级温度范围,可适应户外低温、室内高温等复杂环境;
  • 封装尺寸:SMD-18P表面贴装,适合批量自动化生产,适配各类小型化设备。

三、丰富的外设接口

模块提供6类常用接口,满足不同场景的外设扩展需求:

  • UART:通用异步收发器,支持串口通信,可连接MCU、传感器、蓝牙模块等;
  • I2C:两线串行接口,适合连接加速度计、温湿度传感器等低功耗外设;
  • SPI:高速串行外设接口,可对接SPI闪存、OLED显示屏等高速设备;
  • PWM:脉冲宽度调制,可用于LED亮度调节、小型电机转速控制;
  • I2S:音频串行接口,支持麦克风输入、扬声器输出(如简易智能音箱);
  • GPIO:通用输入输出口,可扩展按键、指示灯、继电器等基础外设。

四、典型应用场景

基于模块的性能与接口特性,可广泛落地于以下场景:

  1. 智能家居:智能灯、智能插座、温湿度监测节点、智能门锁等;
  2. 工业物联网:远程设备状态监测、环境数据采集(温度/压力)、小型工业网关;
  3. 消费电子:智能玩具、穿戴设备(手环数据传输)、小型智能音箱;
  4. 户外监测:农业大棚温湿度监测、气象站数据传输(支持-40℃低温);
  5. 物联网网关:小范围多设备数据汇聚,转发至云端平台。

五、开发与集成优势

ESP-WROOM-02-N2在开发与集成上具备明显优势:

  • 开发便捷:乐鑫提供完整SDK、示例代码及技术文档,社区活跃(国内开发者社区成熟),问题解决效率高;
  • 集成度高:板载天线+射频前端,减少外部元件(无需额外WiFi芯片、天线),降低PCB设计复杂度;
  • 稳定性强:工业级温度范围+高接收灵敏度,适合长期稳定运行(如7×24小时监测设备);
  • 成本可控:ESP8266系列成熟量产,模块成本适中,适合批量应用(如智能家居单品大规模出货)。

该模块凭借平衡的性能与成本,成为物联网入门级WiFi方案的经典选择,广泛应用于各类需要无线联网的小型设备。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
