ESP-WROOM-02-N4 WiFi模块产品概述

一、核心芯片与无线传输性能

ESP-WROOM-02-N4搭载乐鑫自研ESP8266EX核心芯片,支持IEEE 802.11b/g/n无线协议,工作频率覆盖2.4GHz~2.5GHz ISM频段,兼容主流WiFi设备(如手机、路由器)。其无线性能参数突出:

  • 发射功率达20.5dBm,在同类模块中处于较高水平,可实现更远距离的稳定传输(典型室内覆盖半径≥20米,户外开阔环境可扩展至50米左右);
  • 接收灵敏度为**-98dBm**,弱信号环境下仍能保持可靠连接;
  • 采用板载PCB天线设计,无需额外外接天线,既简化硬件布局,又保证射频性能一致性,适配空间紧凑的产品。

二、丰富接口与紧凑封装

模块提供3类常用接口,可灵活对接各类外设:

  • I2S接口:支持音频数据传输,适用于智能音箱、语音交互设备;
  • I2C接口:可连接温湿度传感器、加速度计等低功耗外设,实现数据采集;
  • UART接口:兼容传统串口设备,便于与单片机、PLC等控制系统通信。

封装采用SMD-18P表面贴装形式,尺寸紧凑(约10mm×12mm),可直接焊接于PCB板,无需插件,降低生产工艺复杂度,适配小型化、轻量化产品(如智能手环、小型传感器节点)。

三、电源与宽温工作参数

ESP-WROOM-02-N4的电源与环境适应性优异:

  • 工作电压:2.7V~3.6V,覆盖锂电池(3.7V典型值)、线性电源输出范围,供电设计灵活;
  • 工作电流:接收状态56mA,发送状态170mA,属于同类WiFi模块低功耗水平,适合电池供电的便携式设备;
  • 工作温度:-40℃~+85℃,可稳定运行于工业控制柜、户外监测设备(如农业大棚、气象站)等极端温度场景,无需额外散热/保温设计。

四、典型应用场景

该模块凭借集成度高、接口丰富、宽温适配等特点,广泛应用于:

  1. 智能家居:智能灯、插座、门锁的WiFi联网,实现远程控制;
  2. 工业物联网:远程监测设备(温度、压力传感器)的数据上传,工业设备状态监控;
  3. 可穿戴设备:智能手环、手表的低功耗WiFi数据同步(如运动数据上传);
  4. 智能家电:空调、冰箱的远程控制与状态反馈;
  5. 户外监测:农业大棚温湿度监测、环境传感器节点的数据传输。

五、产品优势与可靠性

作为乐鑫ESP8266系列经典模块,ESP-WROOM-02-N4具备以下核心优势:

  • 集成式设计:RF收发器高度集成,减少BOM成本与PCB空间;
  • 品牌可靠性:乐鑫成熟的WiFi物联网技术积累,模块经过严格射频测试与可靠性验证;
  • 易开发性:配套完善SDK与开发文档,支持Arduino、MicroPython等开发环境,降低开发门槛;
  • 成本可控:平衡性能与成本,适合中低端物联网产品批量应用。

综上,ESP-WROOM-02-N4是一款高性价比的WiFi物联网模块,兼顾性能、功耗与环境适应性,是工业、智能家居等领域小型化联网设备的可靠选择。

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
