Arducam B0550 GMSL2 12MP Camera Extension Kit for Raspberry Pi

GMSL2 (Gigabit Multimedia Serial Link 2) is a high-speed serial interface standard that uses ADI SerDes chips. It allows the Arducam B0550 to transmit uncompressed, high-bandwidth video data over a single coaxial cable up to 15 meters with ultra-low latency. This is critical for real-time applications like robotics, where delay can impact performance. The interface also simplifies wiring by combining power and data (Power-over-Coax), reducing system weight and complexity compared to multi-cable setups.

Yes, the Arducam B0550 GMSL2 Camera Extension Kit is designed to be backward compatible with GMSL1 systems. This allows for a straightforward upgrade path. You can integrate this higher-performance 12MP camera into an existing GMSL1 infrastructure without needing to replace the entire serial link hardware, provided your host receiver board supports the necessary power and data protocols for the IMX477 sensor's output over the compatible link.

Using the Arducam B0550 with a Raspberry Pi requires specific drivers and libraries to interface with the GMSL2 receiver board and the Sony IMX477 sensor. You will typically need to install Arducam-provided kernel modules and user-space libraries that enable the V4L2 (Video4Linux2) driver framework. Configuration involves enabling the appropriate overlays in the Raspberry Pi's config.txt file and potentially compiling custom firmware to handle the GMSL2 deserialization and sensor control via I2C.

The kit utilizes Power-over-Coax (PoC), where power is delivered alongside data on the single coaxial cable. The specific voltage and current requirements are provided by the GMSL2 receiver board to which the camera connects. You must refer to the receiver board's datasheet for exact input power specs, typically in the range of 5V or 12V. The receiver board then regulates and supplies the correct power to the camera module through the coax, simplifying your system's power supply design.
