The "2432S028R" designation is a specific model number, but variations exist. The zip file often contains a PDF schematic or an image file showing the pinout. This is crucial because the silkscreen (the text printed on the board) is often minimal or misleading. For example, you might see pins labeled simply as "IO25" or "P1". The schematic found in the zip file clarifies that:
