Rainbow Cube kit - RGB 4x4x4 (Schematic and Data-Sheets)

Hi, I got my hands on the 4x4x4 Rainbow Cube Kit recently but I’m unable to download the schematic and data-sheets, under resources, from the site: https://wiki.seeedstudio.com/Rainbow_Cube_kit_RGB_4_4_4_Rainbowduino_Compatible/#hardware-installation

Any help will be appreciated. Thank you.
