Apple schematic PDF packed in a RAR archive for the A2681 model, listed as the keyboard board KB with number 820-02862 revision 02. Apple uses 820- numbers for its logic and subsidiary boards. A schematic of this assembly helps trace keyboard, trackpad or Touch ID related connections and supply lines and locate test points. Extract and open the PDF in any reader. Compare the 820 number printed on the actual board before relying on it, since related boards carry different numbers.
