If VBUS is used to power the board, populate J53 with jumpers. The voltage for FX3 I/O power domains can be selected using on-board selection jumpers. These domains include VIO1, VIO2, VIO3, VIO4, VIO5, REG_VBATT, and CVDDQ. All other power domains are tied to 1.2 V.A standard Micro B receptacle is used on the FX3 DVK board. VBUS power also comes from the host through this connector.
