Frequently Asked Questions (FAQs)

Q: Is the Zenmuse L3 compatible with the Matrice 350 RTK?
A: No, the Zenmuse L3 is exclusively compatible with the DJI Matrice 400 drone. This exclusivity is due to its higher power consumption (1535 nm 100W laser), its weight of 1.6 kg and the need to use the new gimbal holder specially designed for the L3. The power supply to the M350 nacelle does not meet the requirements of the L3.
