I think you can try this:
Remove the 328.
Power the board from a power supply, and using only the RX and TX lines of an FTDI interface, attach the RX/TX lines to the UART rx/tx lines.

This way you can power everything, and talk directly to the rn52. You'll need a way to ground the CMD pin to force the rn52 into command mode since the 328 won't be there to do that for you. You can just jumper  the digital pin 4 on 328 (physical pin 6) to ground to do that.
