ESP32-WROVER-E-N4R8 多协议无线模块产品概述

一、核心芯片与存储配置

该模块核心采用乐鑫自研的ESP32-D0WD-V3处理器,基于Tensilica LX6双核架构,主频最高可达240MHz,具备多任务并行处理能力,可同时应对无线通信、数据运算等需求。

存储方面采用“64Mbit PSRAM + 4MB SPI Flash”的组合:

  • 64Mbit(即8MB)PSRAM(伪静态随机存取存储器)可扩展系统运行内存,满足复杂固件(如支持多协议栈、机器学习轻量模型)或多传感器数据并发处理的内存需求;
  • 4MB SPI Flash用于存储固件、用户配置及日志数据,容量充足且读写稳定性高。

二、无线性能与协议支持

模块聚焦2.4GHz ISM频段,兼容Bluetooth 4.2协议(含经典蓝牙BR/EDR与低功耗蓝牙BLE),核心无线参数如下:

  • 发射功率:20.5dBm(同类模块中处于较高水平),开阔环境下有效覆盖范围可达50~100米,适合中远距离无线传输;
  • 接收灵敏度:-97dBm,在电磁干扰较强的环境(如工业车间、密集WiFi区域)仍能稳定接收信号;
  • 天线设计:板载PCB天线,无需额外外接天线,既降低系统成本,又缩小整体体积,便于集成到小型化设备中;
  • 电流特性:接收模式约108mA,发送模式约350mA,可配合芯片深度睡眠模式(微安级电流)实现低功耗待机,平衡传输稳定性与功耗需求。

三、丰富接口与功能扩展性

模块提供10余种标准接口,可灵活对接各类外设,覆盖多场景应用:

  • 数字接口:GPIO(通用输入输出)、UART(双串口)、SPI(双SPI)、I2C(双I2C),可连接传感器、显示屏、存储芯片等;
  • 模拟接口:12位ADC(支持多路模拟量采集)、8位DAC(输出模拟控制信号),适合温度、电压监测或电机调速;
  • 专用接口:CAN(控制器局域网)对接工业总线、I2S(音频串行接口)实现音频输入输出、PWM(4路)用于LED调光/电机控制、SDIO(支持SD卡扩展)。

四、封装与工作环境适应性

  • 封装形式:SMD(表面贴装)封装,尺寸18mm×31.4mm,体积紧凑,适合PCB批量贴装,可集成到手持设备、小型网关等产品中;
  • 工作电压:3V~3.6V宽电压范围,常用3.3V供电即可稳定工作,适配多数电源电路(如锂电池、线性电源);
  • 温度范围:-40℃~+85℃工业级温度,可在低温(如北方户外)、高温(如车间烘箱附近)环境下长期稳定运行,满足 harsh场景需求。

五、典型应用场景

凭借高集成度、稳定性能与丰富接口,该模块适用于以下领域:

  1. 工业物联网:通过CAN接口对接PLC、传感器,实现设备状态监测、远程控制;
  2. 智能家居:蓝牙连接家电、温湿度/门窗传感器,构建家居自动化系统;
  3. 智能农业:宽温特性适配户外大棚,采集土壤湿度、光照数据并无线回传;
  4. 远程控制设备:高发射功率支持无人机、机器人的中远距离无线操控;
  5. 智能穿戴(辅助):稳定蓝牙传输可用于智能手环、手表的手机同步功能。

ESP32-WROVER-E-N4R8作为乐鑫推出的高性价比无线模块,以“强运算+大内存+多接口+宽温适配”为核心优势,成为工业、家居、农业等领域的理想无线解决方案。

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
