add-thor-carrier

ACTIVE BUILD

Why

The lab brick and the production SOM are different envelopes, rails, and NVENC counts. Buying the wrong one locks the carrier and the enclosure.

What

  • Lab: AGX Thor Developer Kit = T5000 module
  • Production ceiling: T4000 SOM if HEVC hybrid still fits
  • Capability: hardware-kit

Impact

  • Capabilities: ADDED carrier requirements
  • ADRs: none

User journey & surfaces

No new UI because this is the compute module and its carrier.

Out of scope

  • Sensor SKUs (add-sensor-lens-kit)
  • Resin lid (add-thor-enclosure)
