Lambortech ECM400-Thor vs ECM410-Thor: which Jetson/IGX module does each use, and how do CAN ports and M.2 slots compare?

Question

Rapidflare · Accepted Answer

Both are Lambortech Thor-series robot controllers in the catalog's Robot Controllers group, but they target different modules and differ on CAN count and one M.2 keying detail.

## Module comparison

| Attribute | ECM400-Thor (AI Edge Platform) | ECM410-Thor (Functional Safety AI Platform) |
|---|---|---|
| Module | Jetson Thor — Jetson T5000 128 GB or Jetson T4000 64 GB | NVIDIA IGX Thor T5000, 128 GB memory |
| CAN ports | CAN bus supported; port count not listed in the catalog | 4 CAN ports (up to four FSI CAN buses) |
| M.2 slots | 3 slots — E-key 2230, M-key 2280, B-key 2242/3042/3052 | 3 slots — E-key 2230, M-key 2230, B-key 2242/3042/3052 |

## Key takeaways

- **Module:** The ECM400-Thor is the Jetson Thor platform, configurable with either the Jetson T5000 (128 GB) or the lower-tier Jetson T4000 (64 GB). The ECM410-Thor is built only on the NVIDIA IGX Thor T5000 (128 GB) and positions itself as a functional safety AI platform for robotics.

- **CAN:** Both boards support CAN bus, but only the ECM410-Thor lists a specific port count — 4 FSI CAN buses. For the ECM400-Thor, the CAN port count is not listed in the catalog.

- **M.2:** Both offer the same total of 3 M.2 slots with identical E-key 2230 and B-key 2242/3042/3052 configurations; the only difference is the M-key slot length — 2280 on the ECM400-Thor vs. 2230 on the ECM410-Thor, which affects the physical size of the card you can install there.

For context, the two are otherwise very close on the specs you didn't ask about: both deliver up to 2070 FP4 TFLOPS, one 5GbE RJ45 port, HDMI 2.0, up to five USB 3.2 Type-C ports, PCIe Gen 5, an integrated 6-axis IMU plus 3-axis magnetometer, 20–57 V DC input, the same 100 × 130 mm board size, and JetPack 7.0 support.
