Ps2 Slim Schematic Diagram Upd Link -

: Official schematics for these "late" slims are rare. Most technicians use Board Scans and Unofficial Schematics from community forums like BitBuilt to trace voltage lines (e.g., the 7.5V vs 8.5V switching). Key Circuit Information

These communities have user-generated "reverse-engineered" schematics focusing solely on the UPD power circuit, because Sony’s official diagrams sometimes hide the internal logic of the µPD chip. ps2 slim schematic diagram upd

There are three sub-revisions of the UPD firmware (1.0, 1.1, and 2.0UPD). The schematic notes that 2.0UPD has a different I²C address for the EEPROM (0xA0 vs 0xA2). Always verify the silkscreen near the UPD chip before swapping boards. : Official schematics for these "late" slims are rare
