2-How to put drill on pcb?
3-I want to dedicate unused part of pcb as a GND , I can ı do this?
4-I will use LQFP - 64 microcontroller.Are all LQPF mcu’s same size , for example clearence between pins. So how should be my trace width?Seedstudio supoort 1524 mm trace width.I want to use 0.2 mm trace width , I hope it is not going to be problem.
I will put project documents when I finished.
