STEVAL-MKI103V1 MEMS demonstration board based on the LPY410AL (dual-axis pitch and yaw 100 dps analog gyroscope) Data brief Features Two different working modes: analog (AWM) digital (DWM) RoHS compliant Description The STEVAL-MKI103V1 is a demonstration board designed to provide the user with a complete, ready-to-use platform for demonstration of the LPY410AL product family. The kit includes a sensing element and an IC STEVAL-MKI103V1 interface capable of translating information from the sensing element into a measured signal that can be used for external applications. In addition to the MEMS sensor, the demonstration board uses an ST7 microcontroller which functions as a bridge between the sensor and the PC. This makes it possible to download the graphical user interface (GUI) from the website or to use dedicated software routines for customized applications. The STEVAL-MKI103V1 demonstration board has been designed for use in two different working modes: analog and digital In analog mode (AWM) the microcontroller on the board is disabled and the analog outputs of the device are available to the user on a dedicated connector. This is the default working mode when the power supply is applied either through the USB connector or through the supply connector. In digital mode (DWM) the microcontroller on the board is enabled and it allows the user to digitally acquire the output signals of the device, to see them on the PC through the dedicated GUI, and to control the control pins of the device.
