After reviewing information from both suppliers, both item numbers are indicating the same part – the latest “B01 version” of the Jetson Nano Developer Kit (4GB). An easy way to check from the pictures and product documentation is to see whether the board has two of the MIPI CSI camera headers. The former A02 version of the dev kit only has one camera header.
For details, please review to the User Guide for the Jetson Nano Developer Kit from NVIDIA.
