ESP32-MINI-1U-N4 多协议无线模块产品概述
一、核心硬件配置
ESP32-MINI-1U-N4是乐鑫（ESPRESSIF）推出的紧凑型无线模块，核心搭载ESP32-U4WDH芯片（ECO V3版本），内置4MB Flash die，无需额外外接存储芯片即可满足程序与数据存储需求。模块采用SMD-55P封装，体积小巧，集成IPEX射频连接器，方便外接天线优化信号覆盖，适配对空间要求严格的嵌入式场景。
二、通信协议与接口兼容性
模块支持Bluetooth 4.2协议，可实现低功耗蓝牙数据传输、设备配对等功能；同时具备丰富外设接口，覆盖主流嵌入式系统需求：
- 数字控制类：UART（串口通信）、I2C（短距离设备控制）、SPI（高速外设扩展）；
- 音频处理类：I2S（立体声音频采集与播放）；
- 存储扩展类：SDIO（外接SD卡实现大容量数据存储）。 这些接口可灵活配置，适配传感器、显示屏、音频模块等多种外设，降低系统开发复杂度。
三、射频性能与功耗表现
- 射频性能：工作于2.4GHz ISM免授权频段，发射功率达19.5dBm，开阔环境下有效传输距离覆盖数十米至百米级；接收灵敏度-97dBm，弱信号或干扰环境下仍能保持稳定连接，抗干扰能力突出。
- 功耗参数：接收状态电流112mA，发送状态电流379mA，结合蓝牙4.2低功耗特性，可满足电池供电设备（如智能穿戴、无线传感器）的续航需求。
四、电源与环境适应性
模块工作电压范围为3V~3.6V，与常见锂电池（3.7V）、3.3V线性稳压电源兼容，无需复杂电源转换；工作温度-40℃~+85℃，覆盖工业级环境要求（如户外监测、车载系统），极端温度下仍能稳定运行。
五、典型应用场景
ESP32-MINI-1U-N4凭借紧凑设计、多协议支持与稳定性能，广泛适用于：
- 智能家居：蓝牙网关、智能灯控、环境传感器节点；
- 工业物联网：远程设备监控、数据采集终端；
- 智能穿戴：运动手环、智能手表（蓝牙数据同步）；
- 无线通信：小型无线网关、传感器网络节点。
该模块集成度高、接口丰富、射频性能优异，适合需要紧凑设计与多协议通信的嵌入式系统开发，可快速实现蓝牙无线连接与外设扩展功能。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
