Connect Front Charging with battery

Connect the cables with the USB PCB. Turn on the mouse and check if it is connected properly - a blue light should appear.

Prepare the bottom shell

Place the cables between the screw holes.

Place the on/off switch.

Add the main PCB

Move the on/off switch to make it lock in. Use the big head screws. The front charging cables should not come between PCB and shell or be in front of the sensor.

Add screws to the clips

Use big head screws.

Prepare battery

Take off red adhesive.

Add battery and clips

The clips are supposed to "sandwich" the main PCB. Add the plate screw for the side button PCB and add the battery.

Add the switch PCBs

Pay attention to the orientation of the cable. Use big head screws. The picture shows the HOT SWAP PCBs.

Add SWITCHES if you are using HOT-SWAP

Pay attention to the orientation of the switches.

Add big head screws

These are for the post-travel calibration of left and right click.

Last step

Combine bottom and top shell with the screws shown on the graphic.

Calibration

To calibrate the pre-travel, turn the screws in the clips to the left or right and pull down the mouse buttons or make them less sensitive. This works on G305 and Superlight based mods.
