STEVAL-MKI031V1 multi sensor application board (MuSA)

The MuSA (multi sensor application board) platform is intended to be used to show the possible use of MEMS devices.

The platform is based on an ST7 8-bit microcontroller that handles the signal coming from the MEMS accelerometer on the board (LIS344ALH analog output and all the digital output in 3x3 mm and 3x5 mm packages can be mounted on the PCB).

The four buttons are used for the menu navigation.A mini-USB connector is available to exchange data with the PC, depending on the specific application, and to recharge the internal Li-Ion battery.

STEVAL-MKI031V1主要特性:

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
