1. Introdução
This manual provides detailed instructions for the Arducam 16MP Autofocus Quad-Camera Kit. This kit is designed to interface four 16MP IMX519 autofocus cameras with a single MIPI CSI-2 slot on compatible single-board computers, such as Raspberry Pi and Nvidia Jetson Boards, using the Arducam Camarray HAT.
The system enables synchronized image and video capture from multiple camera modules, expanding possibilities for advanced applications like VR, AR, SLAM, 3D sensing, and image stitching.

3. Instruções de configuração
Follow these steps to assemble and prepare your Arducam Quad-Camera Kit for operation.
3.1 Montagem do hardware
- Connect FPC Cables to Camera Modules: Carefully insert one end of each long FPC cable (UC-593) into the CSI connector on each of the four 16MP IMX519 camera modules. Ensure the blue tab on the FPC cable faces away from the camera lens when inserting. Secure the connection by closing the connector latch.

- Fixe com os acessórios de montagem: Use the provided screws and standoffs to securely mount the Camarray HAT to your host board, if applicable.
3.2 Configuração de Software
Proper software configuration is essential for the kit to function correctly. Ensure your operating system is up to date.
- Raspberry Pi: It is recommended to run the latest version of Raspberry Pi OS (Debian version 11 Bullseye, January 28th, 2022, or later releases). The kit is compatible with the latest Pi camera software (libcamera) and uses the official Pi camera tuning algorithm.
- Jetson Board: The camera is compatible with Jetson Developer Kits. Compatibility with other third-party boards is not guaranteed.
For detailed software setup guides, refer to the official Arducam documentation:
Nota importante:
- The four-channel camera is a customized model that requires the HAT to provide a clock. The individual camera modules cannot be removed and directly connected to a Raspberry Pi without the Camarray HAT.
- At least three of the four cameras must be connected for the system to output any images.
4. Operação
The Arducam Quad-Camera Kit allows for simultaneous image and video capture from all four connected cameras.
4.1 Captura de Imagem e Vídeo
- The system combines four camera feeds into one frame.
- Each individual camera feed has a maximum resolution of 2288(H) x 1736(V).
- The maximum output resolution for still images is 4656 x 3496.
- The maximum output resolution for video is 1920 x 1080.
- Due to the combination of four feeds, the frame rate for both video and still images will be approximately half of what a single camera would typically achieve.
4.2 Autofocus Functionality
Each 16MP IMX519 camera module features autofocus capability, allowing for clear imaging across a focus range of 10 cm to infinite. The autofocus function is managed through the software interface.

Sincronização 4.3
The Camarray HAT enables synchronized capture across the four camera modules. Specifically:
- Images from cameras 0 and 1 are completely synchronized.
- Images from cameras 2 and 3 are completely synchronized.
- Images from cameras 2/3 will be one frame behind the images from cameras 0/1.
4.4 Aplicações
The synchronized multi-camera capabilities of this kit are suitable for various advanced applications, including but not limited to:
- Realidade Virtual (RV)
- Realidade Aumentada (RA)
- Simultaneous Localization and Mapping (SLAM)
- 3D Sensing
- Costura de imagem
- Rastreamento de objetos

5. Manutenção
To ensure the longevity and optimal performance of your Arducam Quad-Camera Kit, follow these maintenance guidelines:
- Manuseio: Handle all components, especially the camera modules and FPC cables, with care. Avoid bending or creasing the FPC cables sharply.
- Limpeza: Use a soft, dry, lint-free cloth to gently clean the camera lenses and circuit boards. Avoid using liquid cleaners or abrasive materials.
- Armazenar: Store the kit in a cool, dry environment, away from direct sunlight, extreme temperatures, and high humidity.
- Proteção: When not in use, consider using a protective case to prevent dust accumulation and physical damage to the camera modules and HAT.
6. Solução De Problemas
This section addresses common issues you might encounter with the Arducam Quad-Camera Kit.
6.1 Problemas e soluções comuns
| Problema | Possível causa | Solução |
|---|---|---|
| No image output or black screen. | Not enough cameras connected, incorrect FPC cable connection, or software issue. | Ensure at least three camera modules are connected to the Camarray HAT. Verify all FPC cables are correctly inserted and latches are closed. Check software configuration and ensure the correct OS version is installed. |
| Individual camera feed is black. | Faulty camera module or FPC cable, or loose connection. | Re-seat the FPC cable for the affected camera. If the issue persists, try swapping the camera module or FPC cable with a known working one to isolate the problem. The composite image will still output, with the failed camera's area appearing black. |
| O foco automático não está funcionando. | Software not detecting autofocus feature or incorrect command. | Refer to the specific software guide for your host board (Raspberry Pi or Jetson) to ensure correct autofocus commands are being used. Ensure your OS and camera software are up to date. |
| Reduced frame rate. | Normal operation for quad-camera setup. | This is expected behavior. The frame rate for video and still images will be halved compared to a single camera due to the processing of four simultaneous feeds. |
| Cameras cannot be used directly with Raspberry Pi. | Misunderstanding of product design. | The 16MP IMX519 cameras in this kit are specifically designed to share clocks with the Camarray HAT for frame-level synchronization and cannot be used as standalone camera modules directly connected to a Raspberry Pi. |
If you encounter issues not listed here, or if the suggested solutions do not resolve your problem, please refer to the official Arducam documentation or contact Arducam support for assistance.
