-As with all STM evaluation boards there is lengthy list of restrictions in place regarding what you can and can't do with an evaluation board. See [[http://www.st.com/st-web-ui/static/active/en/resource/legal/legal_agreement/license_agreement/EvaluationProductLicenseAgreement.pdf|this]] document.+As with all STM evaluation boards there is lengthy list of restrictions in place regarding what you can and can't do with an evaluation board.

 +There are different revisions of this board and the sample here  
 +is the MB997C. One difference between this and the original board 
 +revision MB997B is that they changed the MEMS sensor from the 
 +LIS302DL to the LIS3DSH. The LIS3DSH is now obsolete and has been 
 +replaced by the LIS3DH.

 +ST propose you use jumper leads to fix this oversight.
