ESP32-C3-MINI-1-H4 产品概述
一、简介
ESP32-C3-MINI-1-H4 是乐鑫（ESPRESSIF）推出的低尺寸、高集成度 2.4GHz 无线收发器模块，支持 Wi‑Fi 802.11b/g/n 与蓝牙 v5.0。模块集成 PCB 印制天线，工作频段覆盖 2.412GHz ~ 2.484GHz，适合需要短距无线连接的物联网设备及消费/工业类终端产品。
二、主要参数
- 品牌：ESPRESSIF（乐鑫）
- 工作频段：2.412GHz ~ 2.484GHz
- 无线协议：Wi‑Fi 802.11b/g/n；蓝牙 v5.0
- 发射功率：20.5 dBm（典型）
- 接收灵敏度：-96 dBm（典型）
- 接口类型：SPI（用于与主控通信）
- 工作电压：3.3 V
- 工作温度：-40 ℃ ~ +105 ℃
- 天线形式：板载 PCB 天线（印制线）
- 封装：SMD，尺寸 13.2 × 16.6 mm
三、性能与优势
- 高发射功率与较好接收灵敏度，使得理论链路预算接近 116.5 dB（20.5 dBm − (−96 dBm)），在无遮挡或室内环境中有利于提高通信稳定性与覆盖。
- 板载 PCB 天线省去外部天线设计，便于产品小型化与快速开发；SMD 封装适合自动贴片与批量生产。
- 宽温工作范围（-40 ℃ 到 +105 ℃）满足多数工业与室内消费场景的环境需求。
- SPI 接口可作为主控与无线模块之间的高速命令/数据通道，便于将模块作为外置无线收发单元集成到多种系统中。
四、典型应用场景
- 智能家居与安防（传感器、开关、门锁等）
- 工业物联与远程监控终端
- 无线网关与边缘节点（短距离设备接入）
- 便携式设备与消费类电子（对体积和功耗有中等要求的场合）
五、集成与设计注意事项
- 电源：保证稳定 3.3 V 供电并在靠近模块电源引脚处布置适当去耦电容，减小电源噪声对 RF 性能的影响。
- 天线区与地平面：为保证辐射性能，应遵循模块厂商的天线留空和地平面建议，避免在天线前方和侧面放置大面积金属或 PCB 铜箔。
- 接地与屏蔽：可靠的地平面和合理的过孔布局有助于抑制噪声并保证射频一致性。
- 布线：SPI 信号线尽量短且有良好阻抗控制，避免与高频电源或大电流回路平行布线。
- 认证与测试：虽然模块集成天线并在设计上便于合规，但整机仍需在目标市场进行射频与 EMC 测试与认证（如 FCC、CE 等）。
六、采购与封装
模块为 SMD 可回流焊贴装，尺寸 13.2 × 16.6 mm，适合自动化贴装和大批量生产。选型时建议向乐鑫或授权分销商索取最新的技术文档、参考设计和天线布局建议，以确保产品开发周期和合规性。

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.
