STEVAL-MKI114V1 STMicroelectronics

STEVAL-MKI114V1 Magnetic field probe kit based on the LSM303DLHC Data brief Features User-friendly LSM303DLHC board Complete LSM303DLHC pinout in standard DIL 24 socket Fully compatible with the STEVAL-MKI109V1 and STEVAL-MKI109V2 RoHS compliant Description The STEVAL-MKI114V1 demonstration board is a kit made up of a probe, mounting the LSM303DLHC compass module, which is connected through flat cable to an adapter board designed to make it compatible with the STEVAL- MKI109V1. The device is mounted on the top of a very thin probe, due to its small package size. The probe can be easily used to measure magnetic field intensity, i.e. for finding the source of magnetic field disturbances on a PCB. This is possible thanks to the Unico software that comes together with the STEVAL-MKI109V2 MEMS motherboard and is able to easily show performance and measurement of the STEVAL- MKI114V1. Data coming from the digital compass connected to the board can be read through the PC GUI which is downloadable from the ST.com website.
