Answer: The schematic for the Rev. C version of this board is in the file named 3681_PCB.pdf. After the CY3681 EZ-USB FX2 Development Kit is installed on your PC, the schematic can be found under the directory “C:\Cypress\USB\Hardware\FX2\DEVBD REVC\PCB_Main.”
For older boards, there is a Rev. A schematic in the file named Fx2.pdf. After tools are installed, the schematic can be found under the directory “C:\Cypress\USB\Hardware\FX2\DEVBD REVA.”
