3. Setup Guide

3.1 Assembling the Keyboard

The GMK70 is a barebones kit, meaning switches and keycaps are not pre-installed. You will need to install your preferred 3-pin or 5-pin mechanical switches and keycaps.

1. Install Switches: Using the provided switch puller, carefully align and press each mechanical switch into the hot-swappable sockets on the PCB. Ensure the pins are straight to avoid bending.
2. Install Keycaps: Once all switches are installed, press your desired keycaps onto the switches.

3.2 Connecting the Keyboard Halves

The GMK70 features a split design. The two halves can be used separately or connected.

• Magnetic Connection: The left and right keyboard halves are designed to magnetically bond when placed close together, forming a single unit.
• Wired Connection (Split Mode): To use the keyboard as a single unit with a wired connection, connect the provided detachable coiled cable between the two halves.
