The lightest IP67-rated Jetson Orin NX product in the catalog is the RAIBOARD-ORNX at 285 g — but it's a carrier board, not a sealed computer, so for a small outdoor robot the lightest ready-to-deploy full system is the PCB Arts Helium at 350 g. forecr.io +1forecr.io ↗“Railway-grade carrier board for NVIDIA Jetson Orin Nano / Orin NX”shop.pcb-arts.com ↗“Compact edge AI computer on Jetson Orin NX 16GB”
A couple of nuances worth knowing before you pick:
- The RAIBOARD-ORNX's 285 g is the bare board only — its IP67 and EN61373 shock/vibration ratings are stated as applying only "with Raibox chassis," so the sealed-system weight will be higher. forecr.ioforecr.io ↗“compliance stated 'with Raibox chassis'”
- The Helium is a fully integrated 350 g system: 90 × 85 × 27 mm, IP67, Jetson Orin NX 16GB, 128 GB SSD, 4x GMSL camera inputs, 2x GbE, 12–48 V input, fanless, −40 to 85 °C — a strong fit for a compact outdoor robot that takes vibration. shop.pcb-a...shop.pcb-arts.com ↗“Compact edge AI computer on Jetson Orin NX 16GB; 128GB SSD, 4x GMSL”
Lightest IP67 Orin NX products, smallest first (19 of 23 matching products list a weight; 4 don't):
| Rank | Product | Manufacturer | Type | Weight | Notes for outdoor use |
|---|---|---|---|---|---|
| 1 | RAIBOARD-ORNX | Forecr | Carrier Board | 285 g | IP67/shock/vibration rated with Raibox chassis only |
| 2 | Helium | PCB Arts | Full System | 350 g | Fanless, −40 to 85 °C, 4x GMSL |
| 3 | Alecs G1-1242 NX16 | Allied Vision | Smart Camera | 810 g | Integrated sensor, 24 V input, 65 °C housing limit |
| 4 | Alecs G1-510 NX16 | Allied Vision | Smart Camera | 810 g | Same platform, different sensor |
| 5 | Falcon Vehicle System | Connect Tech | Full System | 1150 g | 9–36 V, CAN FD, GMSL2, 5G, −25 to 70 °C |
Notes on the candidates:
- Helium (rank 2) — the practical winner for a small robot: sealed full system, DIN-rail/wall mountable, 100 TOPS (up to 157 TOPS in Super mode), fanless. shop.pcb-a...shop.pcb-arts.com ↗“DIN rail, Wall mount”
- Alecs G1-1242 NX16 / G1-510 NX16 (ranks 3–4) — these are IP67 smart cameras rather than general-purpose computers, with the Orin NX 16GB built in; their −20 to 65 °C range is a housing temperature limit. alliedvisi... +1alliedvision.com ↗“Housing temperature limit”alliedvision.com ↗“Housing temperature limit”
- Falcon Vehicle System (rank 5) — only 115 × 52 × 152 mm and fanless with CAN FD and ignition-style 9–36 V input, making it very robot-friendly if you can carry the extra 800 g over the Helium. connecttec...connecttech.com ↗“IP67 fanless vehicle edge AI system (ESG615-0Y) with Jetson Orin NX 16GB”
- Two other IP67 Orin NX matches — Blox_V (AI Blox) and e-con Darsi Pro — don't list a weight in the catalog, so I can't rank them against the ones above. ai-blox.com +1ai-blox.com ↗“IP67 passively cooled vehicle-grade AI computer”e-consystems.com ↗“100 TOPS and an IP67 enclosure”
If a carrier-board-plus-custom-enclosure approach works for your robot, the RAIBOARD-ORNX is the absolute lightest path; otherwise the Helium is the lightest sealed, ready-to-run Orin NX system I can verify.
