How to Replace the Daughterboard in ACR Pro Keyboards (ACR Pro 75, ACR Pro Alice, ACR Pro 68)？

Below are the steps to effectively replace the daughterboard:

1. Begin by removing all screws from the bottom case to separate the top and bottom sections.
2. Carefully lift the PCB to gain access to the two screws securing the daughterboard. Be sure to handle this step delicately to avoid disconnecting the JST cable from the PCB. This may cause the pins to bend.
3. Disconnect the JST cable from the existing daughterboard and connect it to the new one. Afterward, reinstall all the screws securely in place.

By following these steps, you can successfully replace the daughterboard in your ACR Pro Keyboard model.
