1.2. Composition

DEBIX Camera Module is composed of camera chip and lens.

• Camera 200A and Camera 500A lenses both contain 1 IR filter and 3 plastic lenses,
• While Camera 1300A lens consists of 1 IR filter and 5 plastic lenses.

1.3. Interface

DEBIX Camera Module’s 24-pin connection interface can be used to connect to the CSI interface of DEBIX Model A/B, or the 24-pin connection interface of camera adapter board for DEBIX SOM A I/O Board. The pin sequence is as shown in the figure:

Figure 4

The interface is defined as follows:

Table 2 Pin definition of 24Pin interface

1.4. Packing List

DEBIX Camera Module packing list:

• 1 x DEBIX Camera Module
• 1 x 24Pin/0.5mm Pitch FPC cable

Chapter 2 DEBIX Camera Module Installation Guide

DEBIX Camera 200A Module, Camera 500A Module and Camera 1300A Module have the same installation connection, so here is an example of Camera 500A Module and DEBIX Model A.

• If you have DEBIX Model B, the installation method is the same, except that DEBIX Model B has a different boot mode than DEBIX Model A. Please refer to DEBIX User Manual for the boot mode.
• If you have DEBIX SOM A I/O Board, you need to install it through an add-on board, please refer to Camera Adapter Board for DEBIX SOM A I/O Board User Manual for details.

WARNING:
Cameras are sensitive to static. Earth yourself prior to handling the PCB. A sink tap or similar should suffice if you don’t have an earthing strap.

2.1. Connect Hardware

• Component Preparation

• DEBIX Model A
• 24Pin 0.5mm Pitch FPC cable
• DEBIX Camera 500A Module

• Hardware Connection

1. Pull up the black rubber snap of the connection interface on the back of Camera 500A Module, insert the FPC cable (note the direction of the gold finger, gold finger facing down), and press the snap as shown in the figure:

Figure 5 Rubber snap being pressed

Figure 6 Rubber Button being pulled up

Figure 8

2. Then pull up the snap of the CSI interface on DEBIX Model A/B, insert the other end of the FPC cable (with the gold finger facing the OTG interface), and press the snap to fix it, as shown below:

Figure 9

1. Connecting finger towards left

Depending on the model, the camera may come with a small piece of translucent blue plastic film covering the lens. This is only present to protect the lens while it is being mailed to you, and needs to be removed by gently peeling it off after installation.

2.2. Power on

Warning
The device can be powered on only after the camera accessories are completely connected; and the accessories cannot be inserted or removed at will during the working process.

1. After connecting DEBIX Camera Module to DEBIX Model A, connect DEBIX Model A to peripherals (keyboard, mouse, monitor), insert a Micro SD card with the latest system of DEBIX Model A, power up DEBIX Model A, then open terminal and run the command:

Important
Running the Cheese tool with an administrator (sudo su), camera boot will fail, so it is not necessary to run as administrator.

2. In the “Take a Photo” window of Cheese tool, you can see the image, press the button to take a picture, and the photo is saved in the path of /home/Pictures; at the same time, you can choose “Effects” to adjust the image window background. As shown in the figure below:

Figure 10

Select “Video” to take a video, select “Burst” to take multiple photos, and click the picture taken below to preview.

Click the icon in the upper right corner of the window and select Preferences to set the resolution of Photo/Video to take photos or videos.
