    Hi Jimmy, 

    The schematic looks good, and I do not expect any issues. Only two comments here.

    1. Make sure to place the capacitors as close as possible to the supply pins in the PCB layout
    2. The ISO3082's A and B pins are internally biased and the additional 2.7kohm pull-up and pull-down resistors are optional. 

    Best,
    Andrew
