    Hello,

    Thank you for your post.

    Our product line is only responsible for the AFE4404. You can create a separate post to have someone review the power circuitry.

    The I2C pins are missing pull-up resistors to the IO_SUP. Please connect 10kΩ pull-up resistors for I2C_DAT and I2C_CLK. You can also use 10kΩ on nRESET for consistency. The remaining connections to the AFE look mostly correct. The decoupling capacitor designators do not match the PCB placement notes, but the values and layout recommendations are ok.

    Regards,

    Ryan
