ST公司的 STEVAL-MKI031V1多傳感器應(yīng)用板是采用ST8 8位微控制器.該平臺可以處理MEMS加速計所產(chǎn)生的信號,板上的密你型USB連接器用來和PC交換數(shù)據(jù).平臺具有128x64象素的黑白LCD,以及MicroSD插座,它的4個按鈕用作菜單導(dǎo)航,主要用來評估各種傳感器.本文介紹了STEVAL-MKI031V1主要特性,方框圖,電路和材料清單(BOM)以及評估板布局圖.
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
