Here's the comparison of the two Seeed Studio carrier boards on power input, MIPI camera inputs, and USB ports:

Key differences:
- Power input: The J401 accepts a wider range starting at 9 V, while the Super J401 requires a minimum of 12 V — so if you're running from a 9–12 V supply, only the original J401 will work.
- MIPI cameras: The Super J401 doubles the CSI camera inputs (4 vs. 2), which matches its description of supporting multi-camera setups with up to 157 TOPS in Super mode.
- USB ports: Both boards offer the same count of 5 USB ports.
A few other points worth noting since you're comparing them: both support Jetson Orin NX and Orin Nano modules, both have 2 M.2 slots, and both are in Active lifecycle status. The Super J401 additionally offers 2 Ethernet ports (vs. 1 on the J401), a mini-PCIe slot, and onboard WiFi/BT with 4G/LTE support.
