== Basic assembly ==

Following this section of the guide, you can assemble the basic camera setup without a screen and a button. This assembly is useful for the OpenCV experiments.

=== Camera mounting plate preparation ===


1. Prepare the camera mount plate, four nuts, and four 10mm spacers

[[File:Stereopi-v2-camera-kit-3.jpg|none|800px|Front plate, 10mm spacers and nuts]]


2. Install the spacer to the hole in each corner and fix it with the nut

3. You should get this assembly as a result:

=== Installation of the cameras ===

Please prepare two cameras, eight nuts, and eight bolts. You will also need the front camera plate assembled in the previous step.

[[File:Stereopi-v2-camera-kit-4-1.jpg|none|800px|Cameras, nuts and bolts]]


Each camera has two metal nuts on the backside of the PCB. Put the camera onto the mounting plate keeping these bolts inside the hole:

[[File:Stereopi-v2-camera-kit-4-2.jpg|none|800px|Camera installation step 1]]

Fix the camera using 4 nuts and 4 bolts:

[[File:Stereopi-v2-camera-kit-4-3.jpg|none|800px|Camera installation step 2]]

Install the second camera the same way. You should get this assembly as a result:


[[File:Stereopi-v2-camera-kit-4-4.jpg|none|800px|Both cameras are installed]]

=== CM4 installation ===

[[File:Cm4 installation stereopi v2.jpg|none|800px|CM4 installation]]

# Disconnect all external equipment and power.
# Put the board upside down so that the USB C port is facing to the left.
# Take the CM4 module so that the triangle PCB antenna and the power circuit (a group of 5 black components) are faced to the left.
# Put the CM4 module on the connectors and gently press the bottom until you hear a click. After that, do the same with the top part of the CM4.

After this step you should get this result:

=== StereoPi v2 power jumper installation ===

[[File:Power-switch-pins.png|none|800px|Power switch pins]]

Install a jumper to the pins near the USB C connector.

=== Connecting cameras to StereoPi v2 ===

For the next step you'll need all items you've just assembled, and also four 20mm spacers.

[[File:Stereopi-v2-camera-kit-6.jpg|none|800px|StereoPi v2 installation]]

While connecting camera ribbons, the first step is gently PULLING black the fixator up 4-5 mm. After that insert camera ribbon by BLUE side to BLACK fixator. Check that the cable is fully inserted at a 90-degree angle. After that push the black fixator down to secure the ribbon.

After this step you should get this result:

=== StereoPi v2 installation ===

You can use camera ribbon cables of different lengths, so this step may vary.
 
Choose the most appropriate ribbon cables' position for your assembly, and put StereoPi v2 board to the spacers, attached to the camera mount plate. Here is how we did it for the 10cm cables:

After that, fix the board using four 20mm stand-offs. Here is the result of this step:

[[File:Stereopi-v2-camera-kit-6-3.jpg|none|800px|Camera mounting plate installed]]

=== Back plate installation ===

Please prepare the assembly from the previous step, backplate, and four nylon bolts:

[[File:Stereopi-v2-camera-kit-7.jpg|none|800px|Backplate installation]]

Attach the backplate to the stand-offs using four bolts. The result should look like this:

=== Tripod mount installation ===

Prepare the GoPro mount add-on and the black acrylic circle from the kit.

[[File:Stereopi-v2-camera-kit-8.jpg|none|800px|Tripod mount installation]]

Install the acrylic circle near the metal part of the GoPro mount first:

[[File:Stereopi-v2-camera-kit-8-1.jpg|none|800px|Tripod mount installation, step 2]]

Install the StereoPi assembly keeping the cameras facing the metal part of the GoPro mount, and fix the assembly using the metal screw included.

== Advanced assembly ==

In this section, we'll review a few cameras installation options, as well as 2" IPS screen installation and a shot button. This assembly is suitable for the SLP2 image and stereoscopic photo/video capture.

=== Elevated installation of the cameras ===

In the first section of the assembly guide, we considered the simple approach of the camera mounting:

[[File:Stereopi-v2-camera-kit-9.jpg|none|800px|Simple assembly]]

If you are planning to experiment with different cameras and want to be able to replace them without the full disassembly, it is better to use the "elevated" camera installation, like this one:


[[File:Stereopi-v2-camera-kit-9-1.jpg|none|800px|Elevated installation of the cameras]]

To do this assembly, use four 6mm spacers and four bolts.

[[File:Stereopi-v2-camera-kit-10.jpg|none|800px|Camera, spacers and bolts]]

Fix the spacers using the bolts:

[[File:Stereopi-v2-camera-kit-10-1.jpg|none|800px|Elevated camera assembly]]

Then install both cameras to the mounting plate:

[[File:Stereopi-v2-camera-kit-10-2.jpg|none|800px|Elevated cameras installed]]

=== Recessed installation of the cameras ===

This method is useful with the StereoPi Slim edition. You can also use it in some specific cases, when you have to hide the cameras' PCB and ribbons behind the mounting plate.

Attach the spacers by nuts this way:

[[File:Stereopi-v2-camera-kit-10-3.jpg|none|800px|Recessed camera installation]]

Install both cameras to the mounting plate:

=== Installation of Pi Cameras V1 and V2 ===

We recommend using the elevated installation of the V1 or V2 cameras.

Since these cameras have another position of the holes, you should use additional holes of the mounting plate.

To simplify the installation difference indication, let us show you both versions of the cameras installed on the same plate.

''Caution: using two cameras with different sensors will cause raspistill/raspivid issues. Please access the cameras using low-level system methods if you really need this mix of sensors for your experiments. In our photo, we are using v1 camera and M12 both equipped with OV5647 sensors, so this couple will work with the raspistill/raspivid without issues.''

=== Screen and shot button installation ===

[[File:Stereopi-v2-camera-kit-12.jpg|none|800px|Screen installation]]

Push the screen's wires through the hole:
