3. Setup Guide
The GMMK PRO is a barebones keyboard, meaning switches and keycaps are sold separately. Follow these steps to assemble your keyboard:
- Prepare Your Workspace: Ensure a clean, well-lit area to prevent dust or debris from entering the keyboard.
- Install Stabilizers (if not pre-installed): The GMMK PRO comes with pre-lubed stabilizers. If you are replacing them, carefully clip them into the PCB.
- Install Switches: Align the pins of your desired 3-pin or 5-pin MX mechanical switches with the hot-swap sockets on the PCB. Gently press each switch until it clicks into place. Ensure pins are straight to avoid bending.
- Install Keycaps: Once all switches are installed, carefully press your keycaps onto the stems of the switches. Ensure they are seated firmly and evenly.
- Connect the Cable: Connect the provided 2M Black Braided USB-C Cable to the USB-C port on the keyboard and to an available USB port on your computer.
