Using an External Battery for VBATT on FX3 DVK (CYUSB3KIT-001) - KBA84130
Can I use an external battery to power the VBATT domain on the CYUSB3KIT-001 FX3 Development Kit (DVK)?
Yes, the VBATT domain can be powered by an on-board regulator or an external battery. To use an external battery with the FX3 DVK Rev. 3 board, insert the battery in the BT1 socket and remove any jumpers on J143 to disconnect the regulator outputs
