Macro camera schematic for the Samsung SM-A23, specifically the 2MP rear macro module, in a 2.79 MB PDF. It maps the connector pins, camera interface lanes, clock and the power rails feeding the sensor. Technicians use it when macro mode is missing or reports a camera error, checking supply voltages and looking for open or shorted filters near the connector. Any PDF reader opens it; verify that the board variant of the handset corresponds to the documented layout before replacing parts.
