Easily mount your FX350 or other 72mm wide board on a surface. Sometimes you just need to mount the board on the wall or in a prop and the environment provides sufficient protection or you don’t have the space. The surface mount adapter will protect the controller’s bottom side and provide an easily maintainable way to mount and adjust your controller as needed. If you need to mount your controller with wood screws, use this. It is NOT recommended to place wood screws (or other course, self-tapping screws) through a PCB. It can damage them and void your warranty.
