The Auvidea JNX45 carrier board has the most USB ports among carrier boards that support the Jetson Nano module family — 7 USB ports. auvidea.euauvidea.eu ↗“io.usb_ports=7”
Here's how the Jetson Nano–compatible carrier boards rank by USB ports (of the 39 in the catalog, 35 list a USB port count; 4 had no value listed and were not ranked):
| Rank | Product | Manufacturer | USB Ports | Notes |
|---|---|---|---|---|
| 1 | JNX45 | Auvidea | 7 | Also supports Orin NX/Nano, Xavier NX, TX2 NX; 2x CSI-2, GbE, CAN, HDMI 2.0 auvidea.euauvidea.eu ↗“Auvidea compact carrier board for Jetson Orin NX / Orin Nano / Xavier NX” |
| 2 (tie) | A216 | Leetop | 5 | Nano-specific industrial board; 4x USB 3.0 Type A + micro USB, HDMI + DP, TF card, -25 to 70 °C, 100x79 mm leetop.cnleetop.cn ↗“4x USB 3.0 Type A + micro USB” |
| 2 (tie) | reComputer J202 | Seeed Studio | 5 | Supports Nano, Xavier NX, TX2 NX; 4x USB 3.1, HDMI 2.1, DP, CAN, 12V DC seeedstudi...seeedstudio.com ↗“4x USB 3.1” |
| 4–9 (tie) | HZHY-AI200_B, HZHY-AI600, JNX43, NX215, VVDN-JN-CB, reComputer J101 | various | 4 | — |
For a classroom setup with lots of USB gear, a few practical observations:
- The JNX45 is the outright USB winner, but note it also lists Jetson Orin and Xavier NX support in its compatibility — if you want a board purpose-built around the original Nano specifically, the Leetop A216 is the top Nano-only option at 5 ports (4x USB 3.0 Type A plus a micro USB for flashing/OTG). leetop.cnleetop.cn ↗“industrial carrier board for NVIDIA Jetson Nano”
- The reComputer J101 (4 ports: 1x USB 3.0 + 2x USB 2.0) is another Nano-only choice from Seeed Studio. seeedstudi...seeedstudio.com ↗“1x USB 3.0 + 2x USB 2.0”
Two things I could not fully determine: the catalog's USB port figure is a total count and doesn't break down USB 2.0 vs. 3.0 for every board (e.g., the breakdown is stated for the A216 and J101 in their descriptions but not for the JNX45), and 4 of the 39 Nano-compatible carrier boards in the catalog have no USB port count listed, so I can't rule out that one of them offers more.
