2.3 Hardware Overview
Three devices, two output types, one ecosystem. Specifications, capabilities, and honest differences.
Device Specifications
All three devices use Multi-SLAM (LiDAR + Visual + IMU). The differences are LiDAR configuration, scan speed, output type, and environment scale.

Three configurations: 16/120, 32/120, and 32/300. First number = channels, second = max range in meters. See model comparison below.
Lixel K1
- LiDAR range0.1 m to 40 m
- Laser classClass 1 / 905 nm
- Scan speed200,000 pts/s
- LiDAR FOV360° × 59° (-7° to +52°)
- Cameras2 × 48 MP panoramic
+ visual positioning
(4 cameras total) - Relative accuracy≤1.2 cm RMSE (3σ)
- Absolute accuracy≤3.0 cm RMSE (3σ, with RTK or GCPs)
- Repeat accuracy≤2.0 cm RMSE (3σ)
- Weight2.2 lbs (1.0 kg)
- Storage256 GB TF card (swappable)
- Operating time~90 min per battery
- IP ratingIP54
- OutputPoint cloud + 3DGS
- Field appLixelGO
Narrower vertical FOV than the L2 Pro. Tilt 15 to 20 degrees forward while scanning so LiDAR covers the floor approximately 5 m ahead.
PortalCam
- LiDAR range0.1 m to 30 m (@10%)
Up to 60 m (@90%) - Laser classClass 1 / 940 nm
- Laser channels96
- Scan speed856,000 pts/s
- LiDAR FOV180° × 180°
- Cameras2 × 12 MP panoramic fisheye
1 × 12 MP front
1 × 12 MP macro
(48 MP total, 4 cameras) - Relative accuracy2 cm RMSE
- Repeat accuracy5 cm RMSE
- Weight1.9 lbs (870 g) without tripod
- Storage512 GB eMMC (internal)
- Operating time~60 min per battery
- GPSSupported (approximate geolocation only)
- Output3DGS only
- Field appLCC Scan
Cannot produce point clouds. Processes through LCC Studio only. The macro camera captures fine detail at 0.27 to 0.55 m depth of field.
L2 Pro Models: 16-120, 32-120, and 32-300
The 32-120 produces the densest point clouds, not the 32-300. Extended range reduces density at the same distance. If your projects are within 120 m and density is the priority, the 32-120 is the better choice.
Map Fusion requires matching L2 Pro models. A 16-channel scan cannot be fused with a 32-channel scan. Confirm model configuration before combining sessions.
Use Cases by Device
L2 Pro: Campus and Large-Scale Projects
Multi-building sites, mixed indoor/outdoor environments, and projects where geometry exists at significant distances from the scanner. Covers tens of thousands of square meters per battery.
- Multi-building campus documentation
- Large commercial interiors and warehouses
- Mixed indoor/outdoor on a single scan route
- RTK or PPK georeferencing projects
- Drone-mounted scanning (DJI M350 RTK and M300 RTK)
- Tunnels and degraded environments (32-300 model)
K1: Single Buildings and Dense Interiors
Optimized for single low-rise buildings and interiors. 40 m range covers most commercial spaces. At 1.0 kg, the lightest option for extended sessions. Swappable TF card extends storage in the field.
- Single-floor and multi-floor interior documentation
- Offices, retail, healthcare, light industrial
- Coverage areas in the range of several thousand square meters
- Projects where low weight and fast deployment are priorities
PortalCam: Visual Documentation
Used when the primary deliverable is a photorealistic 3DGS model, not a measured point cloud. 96-channel LiDAR with 180° × 180° FOV. Weighs 870 g without tripod. 60-minute battery (vs. 90 minutes for L2 Pro and K1).
- Client walkthroughs and virtual tours
- Visual progress documentation
- Spaces where visual quality matters and measurement is not required
The PortalCam cannot produce point clouds. Do not plan a measured-deliverable project with a PortalCam as the only capture device. Use an L2 Pro or K1 for point cloud output.
Despite the name, the PortalCam is a 96-channel LiDAR scanner with full Multi-SLAM. The LiDAR provides spatial structure for 3DGS reconstruction. "Camera" refers to its emphasis on visual fidelity, not its sensor architecture.
Full Comparison
Accuracy conditions matter. Absolute accuracy of ≤3.0 cm requires RTK or GCP coverage with no unfixed gap exceeding 100 m (L2 Pro) or 50 m (K1). Relative accuracy of ≤1.0/1.2 cm applies to post-processed data between points within 100 m. The 3σ qualifier means approximately 99.7% of measurements fall within the stated range.
RTK Modules
The L2 Pro and K1 support RTK via an attachable module. RTK is not built into the base scanner. The module must be attached and configured in LixelGO before the session starts.
Two variants are available. Both support GPS L1/L2/L5, GLONASS L1/L2, BDS B1/B2/B3, and Galileo. Both publish 0.8 cm horizontal and 1.5 cm vertical accuracy (plus 1 ppm baseline correction). The Survey Grade module adds a higher-gain antenna (5.5 dBi vs. 2.8 dBi) for better performance under partial canopy, near structures, and in urban environments.
Full setup: Module 4: RTK Setup and Field Execution. Introduction to when RTK is needed: 4.1 When Georeferencing Matters.
Aerial RTK module. The L2 Pro also supports a drone-specific RTK module. It is not used for handheld scanning.
