    Hello,

    Generally we do not release PCB board files for EVMs. However, if you are trying to recreate this, we do show the Board Layout and Schematics in the User's Guide.

    Regards,

    We may like to buy the EVM. There are no mounting holes. The user guide shows only the top layer.

    I like to find out if we could drill a couple mounting holes without destroying it. 

    Questions about the PCB:

    1. How many layers?

    2. Was there are planes or signals on the corners of the PCB?

    3. Was inner layer flooded with GND copper only but no power planes (especially the corner)?

    Thank you.

    Hello,

    Please see my answers below.

    1) This EVM has 4 layers

    2) There are no signaling on the corners of the PCB, only ground planes.

    3) The 2 inner layers are flooded with ground copper. There are no dedicated power planes since VCCA/VCCB are routed on the top layer.

    Regards,
