Our drone streams lidar over Ethernet. Which drone mission computer has the fastest Ethernet port?

Question

Rapidflare · Accepted Answer

The fastest Ethernet port on any drone mission computer in our catalog is on the **Lambortech RMC-604** — it has **2.5GbE**, and it's the only drone mission computer that goes beyond 1GbE.

Details relevant to your lidar-over-Ethernet use case:

- **Lambortech RMC-604** (RMC-604 NVIDIA Jetson Orin Lightweight AI Drone Computer): max Ethernet speed 2.5GbE, **2 Ethernet ports**, built on Jetson Orin NX 8GB/16GB or Orin Nano 8GB, with 10–60 VDC input for 3S–14S batteries.

For comparison, every other drone mission computer with a stated Ethernet speed tops out at 1GbE — including the SDK Systems UAVNX16-100R, the Lambortech ECM001–ECM004 series, ARK's Just A Jetson and Jetson PAB Carrier, the DJI Manifold 2-G, the Holybro Pixhawk Jetson Baseboard, and Auterion's AI Node and Skynode N.

One caveat worth noting: if you were considering the compact Lambortech ECM001, the base ECM001 variant is only 10/100M Ethernet — the ECM001-GIGA variant is the one with 1G Ethernet.

If you want the 2.5GbE link to actually help, remember the lidar itself and any switch in the path also need to support 2.5G — otherwise the RMC-604 will negotiate down to the slowest link speed.
