Circuit diagram for the Positivo Sim+ X190, built on the Quanta UW3 mainboard at revision 1A, provided as a 1.51 MB PDF. Quanta manufactured many boards for Positivo, and the UW3 project code plus the DA-prefixed number on the PCB confirm compatibility. Technicians use this kind of schematic to trace standby and main rails, check the charger and VCORE stages and locate test points for measurement. Any PDF viewer opens it; verify the 1A revision before trusting part values.
