• A19-A0: The address bus, which carries memory and I/O addresses between the CPU and other components.
• D7-D0: The data bus, which transfers data between the CPU, memory, and I/O devices.
• CLK: The clock signal, generated by the clock generator, which synchronizes system operations.
• RESET: The reset signal, which initializes the system and sets it to a known state.

2. Trace Thickness = Current Capacity

On the top schematic, power traces (Vcc) are drawn wider than signal traces. In the KB 5150, look for:

• Produce a labeled top-side PCB diagram (annotated image) from your Gerber/PCB file, or
• Run an itemized DRC/ERC checklist tailored to your PCB file — upload the Gerber or PCB project files.

The "KB" in KB-5150 stands for Kingboard, the manufacturer of the base PCB laminate. The board is typically made of CEM-1, a composite material consisting of a cellulose paper core and glass cloth surfaces. Power Supply TCL KB-5150 схема
