STEVAL-MKI187V1 Data brief ArgonKey mezzanine board based on different ST sensors Features The following ST MEMS sensors are mounted: LSM6DSL 6-axis inertial module LIS2MDL Magnetic sensor LPS22HB Pressure sensor HTS221 Humidity and Temperature sensor MP34DT05-AMicrophone VL53L0X gesture detector Based on STM32F412C microcontroller Description The STEVAL-MKI187V1 is a mezzanine board (also referred to as 96Boards Argonkey) designed according to the Linaro specification. The board acts as a sensor hub platform for all 96Boards compliant products. The board can be used as a standalone board or connected to the HiKey (LeMaker) board from 96Boards. The board has two buttons (Reset and user) and several LEDs that are appropriately positioned for IoT hardware applications.
