	There was an error discovered in the 10359 & 10359A boards - due to a wrong source the sensors (J2,J3,J4) were powered from the 10359's 2.5V instead of the correct 3V coming from 10353 - the ~~result~~ was almost not noticeable - vertical stripes with a 4-pixel period (~~only with 10338d~~ boards)		There was a design error discovered in the 10359 & 10359A boards - due to a wrong source the sensors connected to J2, J3, J4 were powered from the 10359's 2.5V instead of the correct 3.3V coming from 10353. Because of that the linear regulators on the sensor board could not maintain nominal output voltage (2.5V, 2.8V) and isolate the analog from the digital supplies. Sensor did great job operating in such conditions in such a way that image deterioration was almost not noticeable - very faint vertical stripes with a 4-pixel period on a 10338D board. Older 10338A used different linear regulators and output voltage was slightly higher, so no vertical stripes were visible (but we would still recommend to replace (or fix 10359 boards as the noise level can be reduced when applying correct power).


	The fix should be applied to all ~~10359s~~ & ~~10359As~~		The fix should be applied to all 10359 & 10359A boards.
