ESP32-C3-MINI-1U-H4 产品概述

一、产品简介

ESP32-C3-MINI-1U-H4 是基于乐鑫(ESPRESSIF)ESP32-C3FH4 核心芯片的低功耗、单频 2.4GHz Wi‑Fi + Bluetooth RF 收发器模块。模块尺寸小巧(SMD 封装 12.5 × 13.2 mm),不含天线但提供 W.FL 射频接口,适合对射频性能和空间要求较高的物联网终端、智能家居及工业控制应用。工作温度范围宽 (-40°C ~ +105°C),工作电压 3.0V ~ 3.6V,兼顾便携电源与稳压供电场景。

二、核心特性

  • 核心芯片:ESP32-C3FH4(基于 RISC-V 内核,支持多种外设接口)
  • 无线协议:Wi‑Fi 802.11 b/g/n(2.4GHz),Bluetooth 5.0
  • 频率范围:2.412 GHz ~ 2.484 GHz(覆盖 Wi‑Fi 信道 1–13)
  • 发射功率:最高 20.5 dBm(典型),接收灵敏度:-104 dBm
  • 工作电压:3.0 V ~ 3.6 V
  • 发射电流(峰值):约 350 mA;接收电流:约 82 mA
  • 接口类型:I2C、JTAG、UART、SPI、USB、I2S
  • 封装与连接:SMD 封装,尺寸 12.5 × 13.2 mm;外接天线通过 W.FL 接口
  • 工作温度:-40°C ~ +105°C

三、射频与性能说明

  • 发射性能优异:20.5 dBm 的输出功率可带来较好的链路预算,适合中短距离通信和穿墙环境。
  • 接收灵敏度达 -104 dBm,可支持低信号环境下的数据接收,利于远端节点或低功耗广播场景。
  • 支持 Wi‑Fi 802.11n 单流(HT20)和 Bluetooth 5.0,适用于同时需要 Wi‑Fi 与 BLE 功能的混合通信设备。
  • 由于模块不自带天线,需外接 50Ω 天线并做好阻抗匹配与射频布局,保证最终 OTA 性能。

四、接口与扩展能力

  • 丰富的外设接口满足复杂应用:I2C、SPI 用于传感器与外设;UART 用于调试与外设通信;USB 可用于供电或数据传输(依设计实现);I2S 适合音频传输;JTAG 提供硬件调试能力。
  • 软件生态:兼容乐鑫提供的 ESP‑IDF SDK(以及常见的 Arduino 封装),便于产品固件开发与 OTA 升级。

五、机械与可靠性

  • 封装形式:SMD,模块尺寸 12.5 × 13.2 mm,适合批量 SMT 安装。
  • 环境适应:工业级温度范围(-40°C ~ +105°C),适合室内外与工业场景下长期运行。
  • 制造与可靠性:建议遵循乐鑫的推荐 PCB 封装与回流焊工艺,注意 ESD 与焊接温度曲线以保证可靠性。

六、典型应用场景

  • 智能家居:智能插座、灯控、门锁与传感网关等。
  • 工业物联网:无线传感器、设备远程监控与数据采集。
  • 可穿戴与便携设备:在满足体积与功耗约束下实现 BLE 与 Wi‑Fi 功能(需考虑电池与峰值电流)。
  • 智慧农业与环境监测:低功耗传感节点与远程数据上报。

七、设计建议与注意事项

  • 电源与去耦:TX 峰值电流可达 350 mA,电源设计需预留足够瞬态能力,主电源旁建议放置低 ESR 电解+陶瓷去耦组合(如 10 µF+0.1 µF),并优化电源走线与地平面。
  • 射频天线布局:保持天线区的 PCB 金属与走线避让,提供 50Ω 阻抗匹配路径,设立天线附近的 keep‑out 区域,避免靠近大面积金属或高噪声元件。
  • 接地与屏蔽:保证良好地平面、充分 VIA 过孔连接,必要时可考虑外加金属屏蔽罩。
  • 热管理:在高发射占空场景或高温环境下注意模块热累积,合理布局散热路径。
  • 调试与固件:使用 JTAG/ UART 进行开发调试;依据产品需要选择合适的 SDK 与协议栈并进行功耗优化(如蓝牙广播/连接参数、Wi‑Fi 省电策略)。

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
