ESP32-WROVER-E-N16R8 产品概述

一、产品简介

ESP32-WROVER-E-N16R8 是乐鑫(ESPRESSIF)出品的多协议 SMD 模块,采用 ESP32-D0WD-V3 芯片,内置 64Mbit PSRAM(8MB)与 16MB SPI Flash,工作电压 3.0V~3.6V,工作温度范围 -40℃~+85℃。模块尺寸 18 × 31.4 mm,板载 PCB 天线,适合对性能、存储与体积有综合要求的嵌入式无线应用。

二、核心特性

  • 无线频段:2.4 GHz(多协议支持,包含 Bluetooth 4.2)
  • 发射功率:最大 20.5 dBm
  • 接收灵敏度:-97 dBm
  • 发射电流:约 350 mA;接收电流:约 108 mA
  • 芯片:ESP32-D0WD-V3,支持丰富的外围接口与双核/单核运行模式(按固件配置)
  • 存储:64Mbit PSRAM + 16MB SPI Flash,为图像缓存、大模型或文件系统提供空间

三、外设与接口

模块暴露常用总线与接口,便于外围器件连接与系统扩展:

  • I2C、SPI、UART(多路)、SDIO、GPIO(多路)
  • ADC、I2S(音频输入/输出) 这些接口可用于传感器、外存、音频编解码器、摄像头、显示器等外设的直接驱动。

四、电源与性能要点

  • 推荐工作电压:3.3V(范围 3.0V~3.6V)
  • 设计时需留足峰值电流余量:发射瞬时电流可达 350 mA,建议电源供应及旁路电容设计能承受峰值并降低电压跌落。
  • 低功耗模式与唤醒策略可用来优化电池供电系统的续航表现。

五、天线与封装

  • 天线形式:板载 PCB 天线,已布局匹配网络,便于直接贴片上板使用。
  • 封装与安装:SMD 封装,18×31.4 mm,便于自动贴装与批量生产。设计 PCB 时请遵循天线周围的保持区与接地规则以保证射频性能。

六、典型应用场景

  • 智能家居与网关设备(蓝牙外设桥接、传感器聚合)
  • 工业控制与远程采集(宽工作温度保障稳定运行)
  • 语音与音频设备(I2S 支持、外部编解码器接口)
  • 需要较大运行时内存或缓存的边缘计算与图像处理场景(PSRAM 与大容量 Flash)

七、设计建议与注意事项

  • 电源设计:模块需稳压 3.3V 并配备 100 µF 以上的去耦电容,近端放置低 ESR 电容以抑制发射瞬态。
  • 天线布局:天线区域保持无大面积金属或地铜,建议遵循厂商的参考布局与保持区尺寸。
  • EMC 与认证:量产前进行 EMC、射频合规测试;若需进入特定市场,确认所需的认证(如 CE/FCC)要求。
  • 软件支持:建议使用官方 ESP-IDF 或兼容 SDK 进行固件开发,以充分发挥芯片与模块能力。

ESP32-WROVER-E-N16R8 在尺寸、存储与无线性能之间提供了良好的平衡,适合对多接口、高速缓存与可靠无线连接有明确需求的嵌入式产品开发。

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
