Does anybody know if this can be a problem?

I am just starting to work with the PSoC 4. It is very interesting, and feels as a professional device. While running my sample codes I notice two resistors in the board almost touching each other. Wonder what they are for and if this could be a problem latter on. Just know I have only run the Cap+RGB led sample and it is working perfect. So I do not see any problem so far with those resistor touching if it is the case.

Has anybody else seen this situation? Seems like they moved a little while soldering. Included two pictures, one with just the resistors and the other with a green rectangle showing the area.

Comment if anybody knows what those are for.

    HI Javier, Looking at the pioneer board schematic R8 and R9 are pullups for the I2C lines. In your case the side where they have pulled together is VDD for both of them, so while it is an assembly fault…

    Great!, thanks. It is working very good. I am using some UART without any issues.

    Javier, Good catch. Looks like a manufacturing line defect, although in this case it should not impact any functionality since the shorted side is the VDD for the pull-up resistors, as Anthony mentioned…

    HI Javier,

     

    Looking at the pioneer board schematic R8 and R9 are pullups for the I2C lines. In your case the side where they have pulled together is VDD for both of them, so while it is an assembly fault it shouldn't cause you any concern.
