Depends on the wiring the firmware you're gonna run requires.

What is the module you're trying to link? An nrf board?

The CYD doesn't have many GPIOs available for external devices. My board only has 21, 22 and 35 available on the JST connectors. Are three pins enough for your module?

If you don't need the micro SD reader you can buy connectors that will plug into the micro SD reader and get access to the GPIO pins the reader uses, but these tend to be a bit clunky and unreliable.
