So last session after finishing the pcb i opened the fusion autodesk and it was blank after spending 2 days on fixing the issue i finally did it but understand that the PCB is wrong so firstly it was really ugly the PCAs mounting is really bad and i decided to make new one

updates

• i decided to add second Xl4016 because i figured out that the one xl can handle only 8A but 18 servos require a lot more so i put second one 1 Xl4016 for 1 PCA9685
• added some capcitors for smoother performance
• added LEDs
• added DIOD for protection
• i also added mounting holes for whole pcb and PCAs with MPU just in not this photo of schematics

so overall i think this design of PCB is gonna be a way better at least because i reasearched and figured out my problems
