To enable a high-quality camera module to be used in applications with restrictions on size and weight, Arducam has just released this small camera module for Jetson Nano/Xavier NX. This is fully compatible with the Raspberry Pi V2 module size, a 24mm x 25mm IMX4477P camera board and a distortion-free M12 mount lens. These camera modules are used natively on each Jetson Nano/Xavier NX with hardware ISP functions.  This camera relies on kernel drivers to function - a kernel version, a camera driver.Versions older than JetPack 4.3 (L4T 32.3.1) are not supported.Upgrading or downgrading your operating system will cause a kernel bump, and you will need to reinstall an appropriate driver.Future JetPack/kernel updates require future drivers. If this happens, please give us some time to process it. And if you don't see it in time, please remind us.NOTE ON THE IMX477 MIPI LANESThe IMX477 camera module supports 4 lanes in hardware, but the 4-lane camera driver requires additional adjustments. Here's the reason:Standard Raspberry Pi and Jetson Nano/Xavier NX cannot physically support a 4-lane connection (both have only 2-lane CSI connectors). Only the Raspberry Pi Compute Module and some third-party Jetson Carrier Boards have 4-lane hardware support. Therefore, this is not a general need.A 4-lane connection requires additional work, especially camera drivers, in addition to the 4-lane physical port. And the drivers are limited by the performance of the platform itself. For example, 4-Lane cannot unlock 4k video on the Raspberry Pi because the VideoCore does not currently support it. Even the Jetson Nano is limited to some extent by the encoding possibilities. You need to make sure you really need it.This text is machine translated.
