How can I use gpio that CLAC does not use, for my push buttons?

Question

My DIY voice recorder had some buttons to control record start & stop.

To replace USB microphone to MAX9414 Microphone Amplifier, I bought CLAC board.

OMG!!

CLAC board eat all gpio pins.

So, I can't connect & control my start & stop buttons.

I founded gipo pins not used by CLAC in the user manual.

Do you think that soldering button lines and very short pins out from CLAC is possible?

I am afraid of making breakdown of CLAC.

Please, help me!!!! TT

Anybody has a good idea for me?

You can pick up the unused GPIOs from the J2 header on the board if you want to avoid soldering. See page 2 of the schematics. so long, Hias
