The 2nd Gen.Arduchip Stereo Camera Solution available in 4 styles and customization

Arducam’s breakthrough in simultaneously connecting more than one camera on regular Pi/NVIDIA Jetson boards started in 2019 – when the Arducam stereo camera HAT is released to connect two cameras and synchronize them at clock level by I2C broadcasting and oscillator sharing.

The Camarray HAT is the second generation of the Arducam multi-camera HAT solution. It supports the latest RPi 12MP IMX708 V3 camera. Besides, you can choose stereo-camera and quad-camera HAT variations according to your demand for sensors and applications. It now also supports Global Shutter cameras like OV9281/OV9782/OV2311 for machine vision.

UC 512 HAT

Support Raspberry Pi, Jetson Nano/Xavier NX, and more

As long as the MIPI camera module already works on those popular embedded systems. Arducam Camarray makes multiple of them possible.

Support Arducam V4L2 camera drivers that make more image sensors – such as OV9281 and OV2311 – possible for the Raspberry Pi and Jetson platforms.


More Connectors, More Possibilities

Arducam Camarray HAT solution allows you to connect more than one camera to a single MIPI CSI-2 camera interface. For example, it’s now possible to connect and sync up to 4 camera modules on a standard Raspberry Pi.

If you have more MIPI interface available on your processing board, the Arducam Camarray solutions are able to bring you even more possibilities to interface multiple cameras. Let’s say your Jetson carrier board comes with 2 MIPI CSI connectors – we can quadruplex each of them and help interface up to 8 cameras on a standard Jetson carrier board and Raspberry Pi Compute Module.

Give and Take

While the computing power of the embedded system remains the same, we have some compromises to make when getting more cameras running on more interfaces.

bg 01

Give – What are the limits we have to live with

Limited resolution and framerates with multiple cameras connected via a single CSI connector.

Those embedded systems come with limited camera interfaces for a reason – the system itself has a limited computing power to process the camera work. In other words, the total bandwidth allocated to the camera feed is limited. Therefore, more cameras require fewer frame rates and lower resolutions to work.

bg 02

Take – What are the limits we can break

You get to view and utilize the video feed from more cameras.

The Raspberry Pi 4, for example, only offers a single CSI camera connector. Admittedly, the Raspberry Pi may not be powerful enough to process multiple cameras simultaneously, but that should not exclude us from exploring its possibilities. With Arducam Camarray solutions, we help you expand the physical connectivities so you can build more and better projects.

Important Note on the Arducam Camarray HAT:

The Camarray HAT is not sold alone for the following reasons:

  1. Most of the cameras on the market are not designed for synched stereo uses. We’ve modified our camera modules specifically for the Camarry HAT. Your own V1, V2 or HQ camera modules won’t directly work with it.
  2. The Camarray HAT requires different firmware for different Image sensors that are not natively working with your embedded systems. Your own OV9281 and OV7251 camera modules won’t directly work with it, and they are not easily interchangeable.

Customization is required if you have extra requirements as the following:

  1. You need the camera module to run on other Video Modes and Frame Rates.
  2. You need to trigger the camera with an External Hardware trigger.


Our IMX477 camera module support 4-lane in hardware, but the 4-lane camera driver requires extra customization. Here is why:

  1.  Standard Raspberry Pi and Jetson Nano/Xavier NX can’t physically support a 4-lane connection (both of them only have 2-lane CSI connectors). Only the Raspberry Pi Compute Module and some 3rd party Jetson Carrier Boards come with 4-lane hardware support. Therefore, it’s not a general need.
  2. Extra works, specifically camera drivers, are required for a 4-lane connection other than the 4-lane physical connector. And the drivers are limited by the performances of the platform itself. For example, 4-lane can’t unlock 4k video on Raspberry Pi because the VideoCore does not currently support it. Jetson Nano is also to some extent limited because of the encoding capabilities. You need to make sure you really need it.
