Thermal Drone Comparison: EVO Lite 640T vs EVO II Dual 640T

Autel EVO Lite 640T vs Autel EVO II Dual 640T V3: While both utilize 640 x 512 thermal sensors, they occupy different hardware tiers. The EVO Lite 640T is a sub-1kg portable platform for rapid deployments. The EVO II Dual 640T V3 is a heavy-duty enterprise platform featuring an interchangeable payload system and 360° obstacle avoidance.

Workflow & Payload Limitations
  • EVO Lite 640T: Fixed payload. Best for routine roof/solar scans where mobility and speed are prioritized.
  • EVO II Dual 640T V3: Modular/Interchangeable payload. Supports external accessories via the top expansion port (e.g., Loudspeaker, Spotlight).
  • Data Handling: Both capture temperature data at each pixel (radiometric) for professional analysis in the Autel IR Tool.

Operational Disclosure: Actual flight times vary based on wind, payload, and temperature. Both aircraft are FAA Remote ID compliant. Commercial operation in the U.S. requires an FAA Part 107 certificate. High-precision accuracy claims for the EVO II series require the optional RTK module.
