STEVAL-MKI031V1 Multi sensor application (MuSA) board platform Data brief Features Multi pole connector for platform expansion using sensor-specific modules 4 buttons for menu navigation 128 x 64 pixel, black and white LCD Piezoelectric buzzer MicroSD socket for data logging applications RoHS compliant Description The STEVAL-MKI031V1 MuSA (multi sensor STEVAL-MKI031V1 application board) platform is intended to demonstrate the performance and possible uses of MEMS devices. The MuSA platform is based on an ST7 8-bit microcontroller, which manages the output signals from the MEMS accelerometer. The platform comes with the LIS331DLH pre- installed on the board, but can support any digital- output accelerometer from ST in 3x3 or 3x5 mm packages connected to the microcontroller through an SPI interface, as well as the LIS344ALH analog-output accelerometer. The MuSA platform features four buttons for navigating the menus. A mini-USB connector is available to exchange data with a PC, depending on the specific application, and also recharges the internal Li-ion battery. The battery is capable of providing power for approximately 7 hours of operation. A USB interface is available for firmware upgrades (DFU), and for exchanging data with user-developed software running on a host PC.
