ESP32-WROOM-32D-N8 产品概述

一、产品简介

ESP32-WROOM-32D-N8 为乐鑫(ESPRESSIF)出品的一款多协议 SMD 模块,内置 ESP32-D0WD 双核 Wi-Fi/Bluetooth 控制器与 64Mbit(8MB)SPI Flash。模块采用板载 PCB 天线、标准化封装(18 × 25.5 mm),支持 UART 串口下载与调试,便于快速集成与量产。工作温度范围宽(-40℃ 至 +85℃),适用于工业与消费类设备。

二、主要规格

  • 核心芯片:ESP32-D0WD 双核 MCU
  • 存储:64Mbit SPI Flash(8MB)
  • 工作频率:2.4 GHz(Wi‑Fi / Bluetooth)
  • 发射功率:20.5 dBm(典型)
  • 接收灵敏度:-98 dBm(典型)
  • 工作电压:2.7 V ~ 3.6 V(建议 3.3 V)
  • 接口类型:I2C、GPIO、SPI、UART(含串口下载)
  • 协议支持:Bluetooth 4.2、802.11 b/g/n(2.4GHz)
  • 天线形式:板载 PCB 天线
  • 封装:SMD,尺寸 18 × 25.5 mm

三、核心特性

模块集成高性能无线与处理能力,支持多协议并行运行,适合对连接与计算有较高要求的应用。20.5 dBm 的发射功率与 -98 dBm 的接收灵敏度提供可靠的链路预算,能够在复杂环境下保持稳定通信。同时,8MB Flash 为复杂固件、文件系统或 OTA 更新提供充足空间。

四、接口与电源

模块提供丰富的外围接口:多路 GPIO、SPI、I2C 与 UART,便于连接传感器、存储与外设。默认支持 UART 模式用于固件烧录与调试。供电要求为 2.7–3.6 V,设计时建议采用稳定的 3.3 V 电源,并在电源输入处增加适当的去耦电容与滤波器以保证射频与 MCU 性能。

五、天线与射频注意事项

模块采用板载 PCB 天线,天线区域须在母板上保持无金属遮挡与较大空白区,周围地平面布局需遵循厂商天线保留区建议。射频引脚为内部匹配好的天线输出,设计时无需外部匹配网络,但应保证 50 Ω 射频走线规范及地平面连续性,以维持最佳 RF 性能。

六、应用场景与设计建议

适用于智能家居、工业控制、可穿戴设备、无线传感与物联网终端等场景。设计时建议:

  • 将天线方向朝外并远离大电流器件与金属结构;
  • 在 3.3 V 供电入口添加 LDO 与足够旁路电容;
  • 对关键 GPIO 做电平与驱动能力评估,必要时使用外部缓冲;
  • 采用串口升级方案简化生产编程与维护。

七、封装与可靠性

模块为 SMD 封装,尺寸紧凑便于自动贴装与回流焊工艺,适合批量生产。工业级的工作温度范围与稳健的射频性能保证在多种应用环境下长期可靠运行。若需进一步硬件规范、模块引脚定义与参考布局,请参考乐鑫官方数据手册以完成符合 EMC 与性能要求的系统设计。

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
