Here's the side-by-side comparison of the PLink-AI 9F1E1 and 8F3E1 on the four attributes you asked about:
| Attribute | 9F1E1 | 8F3E1 |
|---|---|---|
| Weight | 1061 g | 1340 g |
| Ethernet ports | 1 (1GbE) | 2 (1GbE) |
| Max operating temperature | 55 °C | 65 °C |
| M.2 slots | 1 (M-key 2280) | 2 (M-key 2280) |
Summary of the differences: plink-ai.com +1plink-ai.com ↗“mechanical.weight_g=1061 g”plink-ai.com ↗“mechanical.weight_g=1340 g”
- The 9F1E1 is lighter (1061 g vs 1340 g) and more compact at 135 × 74.5 × 166.7 mm. plink-ai.com +1plink-ai.com ↗“mechanical.weight_g=1061 g”plink-ai.com ↗“mechanical.dimensions_mm”
- The 8F3E1 offers more connectivity — a second Ethernet port, a second M.2 slot, plus 2 CAN ports, 2 serial ports, and 4 DIO channels that the 9F1E1 doesn't list. plink-ai.com +2plink-ai.com ↗“io.ethernet_ports=2”plink-ai.com ↗“io.can_port_count=2, io.ethernet_ports=2”plink-ai.com ↗“io.ethernet_ports=1”
- The 8F3E1 handles higher heat, rated up to 65 °C versus 55 °C for the 9F1E1 (both fan-cooled, both 12 V DC, both supporting AGX Xavier and AGX Orin modules). plink-ai.com +2plink-ai.com ↗“thermal.max_operating_temp_c=65 °C”plink-ai.com ↗“thermal.max_operating_temp_c=55 °C”plink-ai.com ↗“thermal.cooling=Fan”
In short: pick the 9F1E1 for lower weight/tighter space, or the 8F3E1 if you need dual Ethernet, dual M.2, and a higher operating-temperature ceiling.
