Hello Everyone,

I have designed a 6-layer PCB. Consisting of the following:
- Pixhawk FC.
- Raspberry Pi CM-04 module
- SIMCOMM 7600 G-H module

The peripherals required include USB 2.0, micro USB, CAN & Serial ports, PWM out pins, and GPIO pins.

PCB layer stack up is as follows.
Top Layer (Red Color): Mixed Signal - Power & Ground Plane.
In1.Cu Layer (Green Color): Solid Ground Plane.
In2.Cu Layer (Orange Color): Signals
In3.Cu Layer (Blue Color): Signals
In4.Cu Layer (Pink Color): Solid Ground
Bottom Layer (Blue Color): Mixed Signal - Power & Ground Plane.

I would like to know what mistakes were made on this and what else can be done to make it a good design.
I've added the pictures below.

Thanks!

Can you make picture of just top and just bottom?
That means for the top, there are no pads and silk screen from bottom visible. Similarly for the bottom.
