Prototype Assembly

This is the assembly guide for the prototype version of the GC Ultimate.

Test Your PCB

Please be sure to test your PCB before proceeding.

  1. Navigate to our configuration app in a Chrome web browser

  2. Connect the PCB with a USB-C cable.

  3. Click ‘Connect’ and select the GC Ultimate device.

  4. Open the Analog and Motion config options to test your hardware. Remap can be used to test button inputs.

Take Inventory

Each base kit for the prototype run should include

  • 6x Torx T8 screws

  • 3x Torx T6 machine screws

  • 3x brass threaded press-fit inserts

  • 5x Torx T6 screws

  • 2x light trigger springs

  • 1x stainless steel octagon gateplate

  • 1x resin octagon gateplate

  • 1x resin round gateplate

  • Upper and lower shell

  • Trigger PCB bracket

  • 2x C-Stick flex cable

  • C-Stick PCB

  • Main PCB

  • 1200 mAh lipo battery

  • 2x trigger membrane assembly

We are also using additional parts listed below, which are separate from the base kit


Align The Rumble Motor

We made a mistake with the silkscreen and the motor location. Sorry!

Locate the motor on the rear of the main PCB.


Gently pry up the motor to release the adhesive.


The motor is designed to align with this cutout in the trigger bracket (see the diagram below).


With the motor loosened, place the trigger bracket in place, making sure to align the motor in the appropriate cutout. Press in the center to ensure the adhesive sticks to the PCB.


Trigger Bracket Assembly

Remove the trigger bracket. Insert the trigger button PCBs into the designated slots on both sides as shown. The wire gets routed through the rear side.

Press the trigger bracket assembly into place on the rear of the main PCB.


Examine the final assembly with both trigger button PCBs in place.


Use two of the Torx T6 screws to connect the main board to the trigger bracket assembly.

Trigger Setup

These steps are repeated for both triggers.

Find the trigger membrane holder, and insert the appropriate membrane as shown.

These two tabs can be trimmed, as resin tolerances make the assembly more difficult. Trim the tabs as shown with a set of flush cutters.

Gateplate Setup

Examine the front shell where the gateplate will be installed.

Locate the three brass inserts. There is a flat side which you will need to insert a screw into as a guide.

Locate one of the T6 machine screws as shown, then screw it into the brass insert. The screw is magnetic, and it will help us to press the threaded insert into the shell.

Repeat this step for all 3 inserts, using the guide below to locate the insertion points.

Remove the screws when you are done.

Process Gateplate

The stainless steel gateplate is polished, however there may still be some burrs or sharp edges on the inner edge. We recommend using a bit of rolled up sandpaper to smooth over any sharp edges.

Front Shell Assembly

Place your buttons into the front shell. In our case we are using the Split Dpad set that we designed and sell on our shop along with the PBT button set which includes the 2 start buttons and dual Z buttons.

Insert the 6 pin flex ribbon cable into the FPC connector with the blue tab facing up.

Ensure the latch is open (up) while installing the cable.

Install the C-Stick cap to the C-Stick PCB at this time.

Install the C-Stick PCB in place as shown. Use the remaining Torx T6 screw to hold the PCB in place. Install the other end of the FPC flex cable and close the latch.

Connect the lipo battery to the main board. Place it in the orientation as shown. The LEDs will begin flashing.

Ensure the trigger analog sliders are in the full up position.

Final Assembly

Carefully place the rear shell in place. There may be some difficulty lining everything up. Take your time and make sure that everything is locked in place properly.

Once everything is pressed together properly, Ensure that you are able to press all of the buttons without anything locking up or getting stuck.

If any buttons get stuck, you will need to go back and ensure there is nothing out of place or misaligned.

Finally, install the 6 Torx T8 screws.
