HLK-B40-I 产品概述

一、产品简介

HLK-B40-I 是海凌科(HI-LINK)推出的一款小型蓝牙无线模块,面向低功耗物联网终端与嵌入式控制应用。模块基于蓝牙5.1协议,工作电压3.3V,封装为SMD,外形尺寸约14×9.5mm,便于表面贴装和批量生产。模块未作细分型号分类,适合作为通用蓝牙连接与控制子系统。

二、主要特性

  • 支持协议:蓝牙5.1,兼容经典 BLE 应用场景与更远的广播/定位特性。
  • 发射功率:最大10 dBm,具备较好的链路覆盖能力。
  • 接收灵敏度:-95 dBm,适合中长距离的低速数据传输。
  • 工作电压:3.3V,便于与常见MCU和外设直接接口。
  • 功能特性:支持OTA空中升级与加密功能,便于后期固件维护与安全性提升。

三、外设接口

模块提供丰富的通用接口,可直接对接外部传感器与控制器:

  • ADC:用于模拟量采样(传感器输入、外部参考测量等)。
  • I2C:标准主/从总线,可连接多种数字传感器和扩展芯片。
  • SPI:高速外设通信,适合外部Flash、显示或高带宽传感器。
  • GPIO:多路通用输入输出,支持中断触发与状态控制。
  • PWM:用于驱动舵机、灯光调光或占空比控制的外设。

在设计时注意为I2C/SPI总线提供必要的上拉电阻和布局留意信号完整性;ADC 输入端应做好滤波与抗混叠处理。

四、安全与固件升级

模块集成加密功能,支持在通信链路中对传输数据进行保护,结合蓝牙安全协议可达到较高的数据保密性。OTA 空中升级功能使得现场设备固件可以远程更新,降低维护成本。建议在系统设计中制定固件签名与版本回滚策略,保障升级可靠性。

五、典型应用场景

适用于智能家居控制器、无线传感节点、可穿戴设备的外围模块、工业监控数据采集、蓝牙遥控器以及需要蓝牙连接与边缘控制的嵌入式产品。凭借小尺寸与多接口属性,在空间受限的产品中具有良好适配性。

六、设计与集成要点

  • 电源:采用稳定的3.3V供电,电源入口处应有去耦电容与滤波网络,防止射频干扰和电压纹波影响无线性能。
  • 天线与 RF 布局:10 dBm 发射功率对天线布局敏感,推荐预留天线匹配区或采用厂方推荐天线,保持模块周围适当的空白地(keep-out)以优化辐射。
  • 接地:建立完整的地平面以降低噪声并改善射频表现。
  • ESD 与信号保护:对外部I/O 添加必要的防护元件,满足工业环境使用需求。
  • 软件:利用模块提供的BLE接口与OTA接口时,建议实现重试、校验和升级回滚,保证长期可靠运行。

七、封装与制造

封装为SMD 14×9.5mm,适合自动贴片与回流焊工艺。建议在PCB上为模块预留对应焊盘及定位标记,并参考厂商的焊接工艺说明以降低焊接缺陷。

八、总结

HLK-B40-I 是一款面向通用物联网与嵌入式控制场景的蓝牙5.1模块,集成多种外围接口、支持OTA与加密功能,具有较高的集成度与适配性。合理的电源、射频与接口设计,将能发挥其在无线连接与边缘控制中的优势,加速产品开发与量产。

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
