Build Process
Step 1: PCD Assembly and Soldering
Take a look at the required components above and determine their final position on the PCB. The following images should be a good reference:
Place groups of components on the board and then solder them to the pads. It is recommended to start with components with the lowest profile, like for example resistor and them move up to components like buttons with higher profile.
To determine the values of the given resistors and to place them in the correct position, please refer to a resistor color code calculator like this one:
Using some form of work holder is advised. You can find a list of suitable work holders on our Recommended Tools List.
We included a pad to put between the regulator (U3) and the surface of the PCB. Use an M3 screw and nut from the kit to mount it.
Step 2: Connecting to the Builder Base
Please refer to the following picture for how we imagined the Joystick could be connected to the Builder Base:
Follow the steps to get everything mounted accordingly:
mount the 9V battery holder to the bottom with M2.5 screws and nuts
free the Builder Base from its case and mount it to the bottom with M2 standoffs and screws
assemble the ribbon cable so it looks like the following
clip a 9V battery into the holder and connect it to the barrel jack with the harness contained in the kit
plug the ribbon cable in and connect the ends to the terminals of the Builder Base by splitting them apart
the ribbon cable connector is labeled and needs to be wired according to how the firmware is set up
We have a 3D file for a joystick case here:

The upper case half case can be mounted to the PCB with 4 M3 screws that are included in the Kit. The lower half gets connected to the upper half with 2 M4 screws that are also included.
Projects
Joystick
The project page can be found here https://quantumintegrate.atlassian.net/wiki/spaces/QHD/pages/1240104961/Joystick%2B-%2BProject.
In this section we will explain how to make the DIY Kit compatible with the project.
After the Builder Base got connected to the bottom of the Joystick, the ends of the ribbon cable can be split and wired into the Builder Base. There is a little dot on the bottom of the PCB next to the ribbon cable connector indicating which pin is the most outer on after the cable is plugged in. Then there is a table explaining which pin is which in or output from the Joystick. Please wire the single wires from the ribbon cable to the client as follows:
SW1 → GP0
Y1 → GP1
X1 → GP2
SW2 → GP3
Y2 → GP4
X2 → GP5
SW3 → GP6
Then 3.3V gets connected which each other, same procedure for GND.
