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。
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:
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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
