Quanta Y0HB board schematic in a 1.07 MB PDF, with no revision, date, brand or platform listed in the file name. Being a variant of the Y0H project, it may share much of its circuit with related boards but should not be assumed identical. Use it to follow power rails, locate components by designator and check connector pinouts during diagnosis. Read the project code on the PCB carefully and make sure it says Y0HB rather than Y0H or Y0HC before trusting values from this drawing.
