【选型】低成本从模式蓝牙模块SKB376与SKB369的对比

时间： 2021-08-10 来源：SKYLAB

技术问答

为满足智能家居、工业控制中的高性价比无线数据传输模块需求，SKYLAB基于国产方案研发推出了一款和SKB369模块Pin to Pin兼容的蓝牙模块SKB376，支持串口到蓝牙透传（只做从机）。

串口蓝牙模块SKB376（只做从机）

SKB376是一个高度集成的蓝牙4.2模组，可用来在2.4GHz ISM频段内做高速率、短距离无线通信。模组基于SYD8811蓝牙无线收发芯片，内部集成32位ARM Cotex-M0处理器，主频64MHz，同时内置32kB RAM和512kB Flash，可以支持模拟或者数字外设。

与串口蓝牙模块SKB369的对比

在方案选择方面，SKB376能完全替代做从的SKB369，且在性价比上完全优于SKB376，需要做从的蓝牙模块可以优选SKB376；

在性能参数方面，鉴于蓝牙芯片SYD8811的发射功率为-94dBm，相比nRF52832方案的-96dBm低2dBm，因此在通信距离上，SKB376会比SKB369短一点；SKB376的休眠功耗比SKB369略高2~3uA。

在应用方面，SKB376可用于电脑输入输出外设、交互式娱乐设备、遥控器、3D眼镜、游戏控制器、健康传感及监控设备、医疗设备、遥控钥匙+手表手环、遥控玩具、室内定位蓝牙信标、彩色遥控LED灯、楼宇自动化、传感器网络、资产追踪。
