Candidate comparison
Specifications are shown only where an identified source supports them. Maximum advertised range is not the same as real-world detection across all target materials.
| Criterion | SLAMTEC C1 [S1] | SLAMTEC A1 [S2] | Waveshare D500 Kit [S3–S4] |
|---|---|---|---|
| Published range | White 70%: 0.05–12 m; black 10%: 0.05–6 m | 0.15–12 m | 0.03–12 m |
| Scan rotation | 8–12 Hz (10 typical) | 5.5 Hz | 6–13 Hz (10 typical) |
| Electrical / interface | TTL UART @ 460800 | 5 V supply, UART 3.3 V level | 5 V supply, UART @ 230400 |
| Package contents | Exact USB bridge: not established | Exact USB bridge: not established | Adapter, USB cable and 4-pin cable listed for kit; verify revision |
| ROS 2 on buyer host | NOT VERIFIED | NOT VERIFIED | NOT VERIFIED |
How to read this matrix
Reflectivity matters: the C1 supplier explicitly separates a 12 m result for 70%-reflectivity white targets from 6 m for 10%-reflectivity black targets. Do not copy “12 m” alone into a purchase acceptance plan.
Names do not prove identical goods: the Waveshare D500 LiDAR Kit is NOT established as the same configuration or source as TANNAI's public TR-LID-D500.
Interface ≠ integration: a UART specification does not prove current ROS 2 driver compatibility, cable contents or host readiness.
