You could use an nRF52840 ItsyBitsy https://www.adafruit.com/product/4481 or Feather https://www.adafruit.com/product/4062 (if you wanted full LiPo battery support) to control it either by digital outputs or serial.

Re: Sounboard fx
OK, I assume you mean one of these boards: https://www.adafruit.com/?q=audiofx&sort=BestMatch.
They can be controlled in two way: by connecting trigger inputs (and volume +/- pins) to ground, or with commands vis the Rx/Tx pins (i.e. a serial/uart interface). for controlling with another board (expecially a 3.3v one) I advise the serial approach as it's more straightforward to wire. See https://learn.adafruit.com/adafruit-aud ... io-control for details, and more generally https://learn.adafruit.com/adafruit-aud ... ound-board.
The idea is that you would use an nRF52840 board to interface with bluetooth and send appropriate commands to the audio board. The serial interface also gives you capabilities like getting a list of files on the board, etc.
