ESP32-C3-WROOM-02-H4 蓝牙/WiFi模块产品概述

ESP32-C3-WROOM-02-H4是乐鑫(ESPRESSIF)推出的一款集成WiFi和蓝牙5.0的RF收发模块,以ESP32-C3为核心芯片,主打高集成度、宽温适应与低功耗,适配智能家居、工业物联网等多场景的无线通信需求。

一、核心芯片与基础定位

该模块搭载乐鑫自研的ESP32-C3 SoC,采用RISC-V架构,将无线通信与基础处理功能整合于一体——无需额外主控芯片即可实现设备控制与无线连接,有效压缩方案体积、降低成本。芯片原生支持WiFi和蓝牙双无线,兼顾中高速数据传输与短距低功耗通信,是物联网设备的高性价比核心选择。

二、无线协议与频段支持

模块支持双无线协议并行工作,覆盖主流通信场景:

  • WiFi:兼容IEEE 802.11b/g/n标准,工作在2.4GHz ISM频段,n模式下最大传输速率达150Mbps,满足视频、数据等中高速传输需求;
  • Bluetooth 5.0:同时支持经典蓝牙(BR/EDR)与低功耗蓝牙(BLE),BLE模式下功耗显著降低,适合长续航便携设备(如可穿戴);
    双无线可同时运行(例如WiFi传云数据、蓝牙连本地外设),互不干扰。

三、丰富接口扩展能力

为适配各类外设,模块提供5类常用接口:

  • 数字通信:2路I2C(连接传感器、显示屏等低速外设)、3路UART(串口通信、程序调试)、2路SPI(高速外设扩展,如SPI Flash);
  • 音频交互:1路I2S(支持音频输入输出,可用于语音控制设备);
  • 调试/供电:USB接口(兼顾程序下载、调试与供电,简化硬件设计);
    接口布局紧凑,硬件开发时可灵活匹配不同外设需求。

四、射频性能参数

射频性能直接决定通信稳定性,该模块表现突出:

  • 发射功率:20.5dBm(约112mW),同类模块中处于较高水平,穿墙或复杂环境下仍能保持信号覆盖;
  • 接收灵敏度:-98dBm(WiFi模式),对弱信号捕捉能力强,抗干扰性能优异;
  • 功耗控制:接收电流82mA、发送电流345mA,BLE模式下功耗更低,适合电池供电设备;
  • 天线设计:板载PCB印制线天线,无需外接天线,节省空间且降低BOM成本,同时保证信号强度。

五、电源与工作环境

  • 电源适配:工作电压3V~3.6V,与常见锂电池(3.7V)直接匹配,无需额外升压/降压电路,简化电源设计;
  • 宽温可靠:工作温度-40℃~+105℃,覆盖工业级环境(如户外低温、家电内部高温),长期运行稳定性高。

六、封装与典型应用

  • 封装形式:SMD-32P(表面贴装32引脚),符合工业标准,适合自动化贴片生产,提升量产效率;
  • 落地场景:
    1. 智能家居:智能灯、插座、门锁(WiFi连网络,蓝牙连手机);
    2. 工业物联网:环境传感器节点(温湿度监测)、远程控制模块;
    3. 可穿戴:智能手环、手表(BLE低功耗长续航);
    4. 智能家电:空调、冰箱的远程控制组件。

总结:ESP32-C3-WROOM-02-H4以高集成度、宽温适应、双无线支持为核心优势,兼顾性能与成本,是物联网设备开发的实用选型。

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
