Schematic in PDF format titled CADIZ-CP, 929 KB in size, with no brand or model given in the name.

Schematics like this let a technician trace power rails, check the power-on sequence and find where a short connects. Before using it, match the project name and board number printed on the PCB with those on the schematic pages.
