The smallest Orin Nano carrier board I found is the Auvidea JNX120, in its JNX120S variant at 24.7 × 75 mm. Auvidea describes it as an ultra-compact drone carrier board, and it works with both Jetson Orin Nano and Orin NX. auvidea.euauvidea.eu ↗“Ultra-compact drone carrier board (JNX120S 24.7x75mm / JNX120M 50x75mm) for Jetson Orin Nano/NX”

I worked out the areas as width × length from the listed sizes. The JNX120 and A603 Carrier Board sizes come from their product descriptions, not a separate dimensions field.
JNX120 at a glance: 2 USB ports, 2 MIPI CSI-2 camera inputs, M.2 M-key 2230 and E-key 2230 slots, 1 Ethernet port, CAN, and 12–24 V input. Its operating temperature, weight and board height are not listed in the catalog. auvidea.eu +1auvidea.eu ↗“io.m2_slots=M-key 2230, E-key 2230, io.usb_ports=2, io.mipi_cameras=2”auvidea.eu ↗“power.power_input_verbatim=12V to 24V”
Things to check for a handheld build:
- Connectors on headers: On the JNX90S, USB runs through internal JST-GH or FPC headers. On the Hadron-DM and Hadron Carrier, USB and Ethernet come out on pin headers. Headers save space, but you would need cabling to reach your enclosure's ports. auvidea.eu +2auvidea.eu ↗“USB connections use internal JST-GH or FPC headers”connecttech.com ↗“with USB and GbE signals routed through pin headers”connecttech.com ↗“USB and GbE signals route through pin headers”
- Cooling on the AIR6N0-C-MB NX: Its 0–60 °C rating only holds with airflow. That could matter in a sealed handheld case. yuan.com.twyuan.com.tw ↗“thermal.operating_temp_condition=Requires airflow”
What I couldn't confirm:
- I couldn't find dimensions for some other compact Orin Nano boards, including Connect Tech's Super Hadron-DM and Leetop's A603. So I can't say whether they would beat these.
- These are bare-board sizes. The installed module and any heatsink will add to the final size.
