The MiiVII APEX THOR has the most serial ports among Jetson Thor box PCs — 6 serial COM ports, the highest count in the catalog. en.miivii...en.miivii.com ↗“io.serial_port_count=6”
Since you mentioned multiple RS-232 sensors on a vehicle, here are all the Thor box PCs with 4+ serial ports:
| Product | Serial Ports | Other vehicle-relevant I/O | Power Input |
|---|---|---|---|
| MiiVII APEX THOR (APEX THOR) | 6 | 4x CAN, 5x Ethernet, 12x GMSL2 cameras, IP65 | 9–36 V |
| Forecr MILBOX-THR | 4 | 4x CAN, 4x 10GbE, 8x GMSL, IP67 | 11–60 V |
| PLink-AI Thor-28F1 | 4 | 4x CAN, 4x Ethernet | 9–36 V |
Why these fit your use case:
- APEX THOR — MiiVII's enclosed embedded AI computer runs the Jetson T5000 module, is rated IP65, and its application domain is in-vehicle telematics, which aligns well with a vehicle deployment. It operates from -25°C to 70°C. en.miivii... +2en.miivii.com ↗“application_domains=in_vehicle_telematics”en.miivii.com ↗“mechanical.ip_rating=IP65”en.miivii.com ↗“thermal.max_operating_temp_c=70”
- MILBOX-THR — Forecr's rugged military-grade unit is designed to meet MIL-STD-810G/461G, DO-160G and IP67, with an isolated CAN FD/serial/DIO set and the widest input range (11–60 VDC). forecr.io +1forecr.io ↗“designed to meet MIL-STD-810G, MIL-STD-461G”forecr.io ↗“isolated CAN FD/serial/DIO”
- Thor-28F1 — the lightest option at 1763 g if weight matters on your vehicle. plink-ai.complink-ai.com ↗“mechanical.weight_g=1763 g”
One note on RS-232 specifically: the catalog tracks total serial COM port count, which includes RS-232, RS-422, and RS-485 ports. For example, the Tauro TT314 and AAEON BOXER units list "RS-232/RS-485" or "RS-232/422/485" interfaces. The exact RS-232 vs RS-422/485 split per port isn't specified in the catalog for every product, so I'd recommend confirming the signal-level details against each vendor's datasheet — linked pages are available via the product listings for APEX THOR, MILBOX-THR, and Thor-28F1. taurotech... +1taurotech.com ↗“RS-232/RS-485”aaeon.com ↗“RS-232/422/485”
If you need more serial ports than any single unit offers, the APEX THOR also has 3x M.2 slots (M/B/E-key) that could host serial expansion cards. en.miivii...en.miivii.com ↗“io.m2_slot_count=3”
