Restructure of PCB Controller Card Layout

The PCB uses a PIC microprocessor, we want to remove some components, improve and change the layout. The PCB has an audio amplifier, opto-coupler isolators , it is around 70mm by 100mm.

For this project we have the Altium project files, schematic and PCB for editing.

Part of the process may require editing of the firmware of the microprocessor.
