SEN0626 Gesture and Face Detection Module failures

I have had two of these units sequentially suffer hardware failures after connection to my Arduino powered device. The software cannot get a device connection when I install either and when I remove them both units show power but will not respond (with their LEDs) to face detection or gesture detection. The first one failed after several hours of working correctly in my device, the second one failed after a few minutes. Is there some weakness I should know about?
