DJI Zenmuse L2
About the DJI Zenmuse L2
The DJI Zenmuse L2 is the second-generation LiDAR payload: tighter ranging accuracy, 5 returns, up to 1.2 M pts/s and a 4/3 CMOS 20 MP mechanical-shutter RGB camera, for Matrice 400, Matrice 350 RTK and Matrice 300 RTK (DJI RC Plus required for M300).
Technical Specifications
| Type | LiDAR + RGB mapping payload |
| Dimensions / Weight | 155×128×176 mm / 905±5 g (28 W typical) |
| Ingress Protection | IP54 |
| Supported Aircraft | Matrice 400; Matrice 350 RTK; Matrice 300 RTK (DJI RC Plus required for M300) |
| LiDAR | 905 nm, detection 450 m @50% / 250 m @10% reflectivity |
| Point Rate | 240,000 pts/s (single) / 1,200,000 pts/s (multiple returns) |
| Ranging Accuracy | 2 cm @ 150 m (RMS 1σ), 5 returns |
| RGB Mapping Camera | 4/3 CMOS 20 MP, mechanical shutter, 24 mm equiv. |
| System Mapping Accuracy | 5 cm horizontal / 4 cm vertical at 150 m in DJI lab RTK FIX + DJI Terra optimized test |
| Detection Range Conditions | 450 m at 50% reflectivity/0 klx; 250 m at 10% reflectivity/100 klx |
| LiDAR Scanning FOV | Repetitive 70°×3°; non-repetitive 70°×75° |
| Mount on M350 / M300 RTK | Single downward gimbal, USB-C right underside port facing nose; incorrect port reduces accuracy |
| Mount on Matrice 400 | Single downward or either dual-downward port; second payload on dual connector reduces L2 mapping accuracy |
| Operating Temperature | -20 to 50 °C |
| microSD | UHS-I U3, sequential write ≥50 MB/s; up to 256 GB |
| Data Source | DJI Zenmuse L2 User Manual v1.2 (official) |

Common Failure Modes
Symptoms: Sparse returns, missing surfaces or lower range than the published controlled-test figure.
Likely areas: Target reflectivity, rain/fog/dust, warm-up, flight geometry and LiDAR window condition.
Compare the actual conditions with the DJI test limits; do not diagnose the transmitter from range alone.
Symptoms: Colorized points or mapping checkpoints do not align as expected.
Likely areas: GNSS/RTK or PPK source, time synchronization, calibration, processing settings and RGB path where fitted.
Review the complete acquisition and post-processing workflow before replacing hardware.
Symptoms: The aircraft does not recognize the LiDAR or gimbal control is abnormal.
Likely areas: Supported aircraft and connector, firmware, power, gimbal and mount.
Power off before inspecting the detachable mount; record the exact aircraft/connector version.
Symptoms: Wet contacts, damaged seals, contamination or visible damage to the optical window.
Likely areas: Housing, window, seals, contacts and storage conditions.
Do not direct-view an operating laser aperture through optical magnifiers; follow the exact DJI manual and isolate damaged equipment.
Repair Notes
Identify L1, L2 or L3 exactly; confirm supported aircraft, connector, firmware and power before diagnosing a payload fault.
Record flight height, scanning mode, target reflectivity, visibility, RTK/PPK status and DJI Terra settings when assessing point-cloud quality.
Power off before detaching the payload. Keep the optical window clean using the manufacturer procedure; avoid direct viewing through magnifiers.
After service, verify recognition, gimbal motion, raw-data recording and a controlled mapping/checkpoint comparison.
