  硬件工具包括一块STM32L4+微控制器开发板,板载意法半导体的各种MEMS传感器,以及STSAFE-A110安全单元、Bluetooth® 4.2 模块、Wi-Fi®模块,以及用于低功耗上云的有印刷天线的NFC标签。配备了X-CUBE-AWS v2.0 STM32Cube Expansion Pack软件包,该开发套件可用作参考设计,简化和加快最终产品的开发。

  X-CUBE-AWS v2.0扩展软件包确保在STM32Cube开发环境内正确集成FreeRTOS 标准AWS连接框架,用户只使用FreeRTOS和STM32Cube即可开发节点软件,无需使用其它软件。软件包还支持AWS原生服务,包括标准的固件无线更新(FOTA)服务,能够处理微控制器与STSAFE-A110安全单元的交互,包括处理AWS IoT 内核多账户注册和在启动、设备验证和OTA固件验证期间分配安全关键运算。

  STM32L4+板能够满足市场对物联网节点的性能和能耗要求,STM32L4S5VIT6超低功耗Arm® Cortex®-M4微控制器集成2MB 闪存、640KB RAM、数字和模拟外设,以及硬件加密加速器。板载传感器包括HTS221容性数字相对湿度和温度传感器、LIS3MDL高性能3轴磁强计、LSM6DSL 3D 加速度计和3D陀螺仪、LPS22HB数字输出绝对压力气压计,以及VL53L0X飞行时间和手势检测传感器和2个数字全向麦克风。

  B-L4S5I-IOT01A Discovery现已上市。
