Update PCB Design for RS485

We need to update our PCB design. It uses RS485 serial communication and the RS485 chip keeps blowing out. It needs better isolation. The board was originally designed in Eagle, but I can send you the files. We need someone that can update the board design and improve the reliability of the RS485 circuit.

Skills: Circuit Design, PCB Layout
