STEVAL-MKI211V1K Data brief 3D digital accelerometer sensor kit based on LIS25BA Features User friendly LIS25BA board Complete LIS25BA pinout for a standard DIL 24 socket Fully compatible with STEVAL-MKI109V3 motherboard Double-sided adhesives included for easy mounting on equipment to be measured RoHS compliant Description The STEVAL-MKI211V1K evaluation board has an embedded LIS25BA 3D accelerometer which is connected through flat cable to a simple adapter board (STEVAL-MKIGIBV3) to render it compatible with STEVAL-MKI109V3. The sensor is soldered precisely in the center of the board and double-sided adhesives are provided to allow users to conveniently mount the board on equipment destined for vibration analysis. Alternatively, you can mount the board using the holes located in each corner of the PCB. The STEVAL-MKIGIBV3 can be plugged into a standard DIL 24 socket. The kit provides the complete LIS25BA pin-out and comes ready-to-use with the required decoupling capacitors on the VDD power supply line. This adapter is supported by STEVAL-MKI109V3 motherboards with high performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface (Unico Product summary GUI), or dedicated software routines for customized applications. 3D digital accelerometer STEVAL- sensor kit based on MKI211V1K LIS25BA LIS25BA - MEMS digital output motion sensor: low noise, high bandwith, 3- LIS25BA axis accelerometer with TDM interface ST MEMS adapter motherboard based on STEVAL- STM32F401VE MKI109V3 compatible ST MEMS adapters Internet of Application Things DB4042 - Rev 1 - December 2019 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-MKI211V1K Schematic diagrams 1 Schematic diagrams Figure 1.
