ESP32-S2-SOLO-2-N4 产品概述

一、产品简介

ESP32-S2-SOLO-2-N4 是基于乐鑫 ESP32-S2 ECO1 核心的表面贴装 Wi‑Fi 模块,集成 4 MB SPI Flash 与板载 PCB 天线,遵循 802.11 b/g/n(2.4 GHz)标准。模块封装为 SMD-41P,面向低功耗物联网、智能终端与嵌入式设备,提供丰富的外设接口,便于快速集成与量产。

二、核心特性

  • 核心芯片:ESP32‑S2(ECO1 版本,单核 Xtensa 平台)。
  • 无线:2.4 GHz Wi‑Fi(802.11 b/g/n),板载 PCB 天线。
  • 发射功率:最大 19.5 dBm;接收灵敏度:-97 dBm。
  • 存储:4 MB SPI Flash(用于固件与文件系统)。
  • 接口:SPI、I2S、USB、I2C、UART 等常用外设接口。
  • 封装:SMD-41P,适合自动贴装生产。
  • 品牌:ESPRESSIF(乐鑫)。

三、接口与引脚

模块提供标准的数字与总线接口,满足传感器、显示、音频与外设扩展需求:

  • SPI:闪存与外设通信或高速外设扩展。
  • I2S:音频采集/播放接口(用于麦克风、扬声器、语音应用)。
  • USB:支持芯片内置的 USB 功能,便于固件下载与通用通讯(注意 PCB 布局与 ESD 保护)。
  • I2C、UART:常用于传感器、MCU 互联与调试。
    在设计时请参考乐鑫官方引脚映射与复用限制,避免多路复用冲突。

四、电气与射频参数

  • 工作电压:3.0 V ~ 3.6 V(典型 3.3 V)。
  • 发送电流:约 310 mA(峰值,发射时)。
  • 接收电流:约 71 mA。
  • 发射性能与接收灵敏度满足多数室内物联网应用对覆盖与链路的需求。
    注意电源设计需覆盖 310 mA 峰值并保证稳定,建议使用低 ESR 电容与良好供电路径。

五、工作环境与功耗

  • 工作温度范围:-40 ℃ ~ +85 ℃,适用于工业级环境。
  • 节能:ESP32‑S2 支持多种低功耗模式(待机/睡眠),在电池供电场景下可通过固件优化功耗与唤醒策略实现长期运行。

六、典型应用场景

  • 智能家居网关与终端(Wi‑Fi 传感、遥控、状态上传)。
  • 语音/音频设备(基于 I2S 的麦克风阵列或扬声器)。
  • 工业遥测、环境监测终端。
  • USB 接口的调试/固件升级设备与数据采集器。
  • 智能照明、智能插座等需要 Wi‑Fi 连接的消费电子产品。

七、设计与兼容建议

  • 天线:保留模块天线周围的空白区(建议半径 ≥ 10–15 mm),避免金属件或大面积地线覆盖天线区域以免影响辐射性能。
  • 电源去耦:靠近模块电源管脚放置 0.1 μF 与 10 μF 去耦电容,并保证电源线宽度与回流路径良好,能承受 310 mA 峰值。
  • 接地与散热:加大模块下方地面铜箔并通过孔与底层地平面连接,利于散热与射频地平衡。
  • USB 与 ESD:若使用 USB 功能,按规范加装差分对走线、滤波与 ESD 保护元件。
  • 天线调试:量产前应做天线场测试与发射功率验证,确保满足当地法规与性能要求。

八、封装与采购信息

  • 型号:ESP32‑S2‑SOLO‑2‑N4。
  • 封装形式:SMD‑41P,适用于回流焊工艺。
  • 厂商:ESPRESSIF(乐鑫)。
  • 提示:模块为完整的 Wi‑Fi 子系统,集成射频与闪存,便于缩短开发周期。量产前建议与乐鑫资料核对最新硬件参考与认证要求。

如需硬件参考原理图、封装图或射频布局示意,可提供具体需求以便给出更精确的布局与元件选择建议。

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
