Schematic PDF, 1.04 MB, for Sony board MBX-238, designed by Wistron under the Tucana project name. Sony uses MBX numbers for its boards, while Wistron, the ODM here, typically names projects after stars and constellations. Technicians use these sheets to follow power rails and the power-on sequence, check charger and VRM circuits, find test points and verify component values near a short. Check that the MBX number and revision on the PCB match the document; any PDF reader opens it.
