Test the Key Presses

When you connect the left side to the computer, short the hotswap socket pads to trigger key presses with a wire or a pair of tweezers.

Solder the Right Side

Repeat the above steps for the right hand side. Test the keyboard by connecting the TRRS cable, and the left hand side to the computer. As a reminder, do not plug/unplug the TRRS cable when the keyboard is powered.

Hotswap Sockets

After testing both sides, solder the hotswap sockets.
