Final release schematic for the Floris Yebisu NB8511 and NB8512 main board, version V4, packed as a PDF inside a RAR archive. The circuit diagram is useful for following power rails, standby and sequencing signals, charging and clock circuits while diagnosing a dead or unstable board. Pair it with the matching V4 boardview to move from a schematic reference to the physical part location. Open the extracted PDF in any viewer, and confirm the PCB version matches before trusting resistor or capacitor values.
