Camera Adapter Board for DEBIX SOM A I/O Board Introduction
Camera Adapter Board is an add-on board designed for DEBIX SOM A I/O Board to allow the connection with DEBIX Camera Modules. It connects to the MIPI CSI interface of the DEBIX SOM A I/O Board via the CSI cable, and connects to the DEBIX Camera Module via the FPC cable.
Main features:
- Double-row CSI connection cable
- Designed for DEBIX SOM A I/O Board
- Compatible with DEBIX Camera 200A, Camera 500A and Camera 1300A
1.1. Overview
Camera Adapter Board has two connectors. DEBIX SOM A I/O Board can be
connected to the DEBIX Camera Module via the Camera Adapter Board, which is
composed as follows:

I/O Interface|
---|---
Connector| 1 x 24pin/0.5mm Pitch FPC socket
1 x 20pin/1.25mm Pitch MIPI_CSI socket
1.2. Interface
The Camera Adapter Board provides two interfaces:
One is a 24pin/0.5mm FPC socket (J1) for connection to the DEBIX Camera
Module.
One is a 20pin/1.25mm MIPI_CSI socket (J2) for connection to DEBIX SOM A I/O
Board.
1.2.1. J1
The pin sequence of J1 is as shown in the figure:
The interface is defined as follows:

1.3. Packing List
- 1 x Camera Adapter Board
- 1 x 20pin/1.25mm Pitch MIPI_CSI cable
- 1 x 24pin/0.5mm Pitch FPC cable
Get Started
2.1. Hardware Installation
The installation procedure is the same for one DEBIX Camera module and two
DEBIX Camera modules, and they are used in the same way; this section
describes the installation of two DEBIX Camera modules as an example.
Component Preparation
1 x DEBIX SOM A + I/O Board
2 x 24Pin/0.5mm Pitch FPC cable
2 x 20Pin/1.25mm Pitch MIPI_CSI cable
DEBIX Camera 200A and 500A Module
Hardware Connection
Warning
The device can be powered on only after all the accessories are completely
connected; and the accessories cannot be inserted or removed at will during
the working process.
-
Pull up the black rubber snap of J1 interface on the camera adapter board, insert the FPC cable that has been connected to the DEBIX Camera 200A Module (note the direction of the gold finger, gold finger facing down), press the snap, and then connect the double-row CSI connection cable to J2 interface, as follows:
-
