Mikroe Hexiwear可穿戴开发套件
MikroElektronika Hexiwear可穿戴开发套件是一款Bluetooth®低能耗(BLE)器件，可用于创建智能手表、远程传感器标签或智能家居控制器。 这种万能器件结构紧凑，将高端器件的风格和可用性都结合在一个开发套件中。 Hexiwear由Kinetis K64 32位ARM® Cortex®-M4 MCU供电，带有NXP传感器。 该可扩展板可与3D加速度计和磁力计、三轴数字陀螺仪、压力传感器和600mA电池充电器封装在一起。 Hexiwear拥有电容性触摸界面1.1英寸全彩OLED显示屏。 通过扩展槽和日益增长的Click板可扩展其功能。 一个Android和iOS应用程序即可将该器件连接到云，无需额外软件开发。 Hexiwear采用FreeRTOS、Kinetis软件开发套件(SDK)和Kinetis Design Studio IDE。
Mikroe has teamed up with NXP to power the Hexiwear with the NXP Kinetis K64 32-bit Arm Cortex®-M4 MCU. The Kinetis KW4x Arm Cortex-MO+ BLE MCU provides connectivity and multiple on-board NXP sensors are included. This expandable board is packed with a 3D accelerometer and magnetometer, 3-axis digital gyroscope, pressure sensor, and 600mA battery charger. Functionality can be expanded with the docking station and the ever-growing line of click boards.
The Hexiwear has a capacitive touch interface 1.1" full-color OLED display. Applications for Android and iOS are available from the Google Play or App Store. The app connects the device to the cloud with no need for additional software development. Hexiwear uses FreeRTOS, the Kinetis software development kit (SDK) and the Kinetis Design Studio IDE.
