I had planned to completely shed the module in resin against the forces.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/23097?ContentTypeID=1Tue, 21 Apr 2015 11:05:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b2720410-fbc4-4b60-aecb-7800f6556153MartinBL<p>I&#39;m sorry, but we haven&#39;t tested this and can&#39;t provide you with any numbers or guarantees. The numbers you mention add up to some serious centripetal acceleration, though. My guess is that your solder joints will crack before the nRF51 malfunctions due to the acceleration. With regards to the BT signals I can&#39;t see any issues with this. Maybe you will see some small fluctuations in range.</p><div style="clear:both;"></div>
