ERDILRF is the product and inquiry website of ERDI TECH LTD, registered in Chengdu, China, and established on 7 May 2021. This facts card lists the company identity, public contact, product-family counts and engineering-document routes. Model specifications retain their source conditions; unresolved source differences require written confirmation for the delivered configuration.

Catalog scope on 22 October 2026
The public catalog contains 59 product records. Complete rangefinder modules and laser-source components are different product types. The 905 platform navigation also contains the separately identified 940 nm LRF10VB sensor; that sensor is not counted as a 905 nm model below.
| Family | Records | Catalog entry |
|---|---|---|
| 905 nm rangefinder / sensor modules | 28 | 905 nm selection guide |
| 940 nm sensor | 1 | LRF10VB |
| 1535 nm complete rangefinder modules | 18 | 1535 nm rangefinder family |
| Erbium-glass laser-source components | 12 | Laser-source family; check exact wavelength per model |
Example module records
| Model / wavelength | Published range and conditions | Module mass | Serial interface | Supply | Published power |

Read each range with its target conditions. Module mass excludes the host assembly. Average power does not define peak rail demand. Open the exact model for its controlled documents and interactive 3D view.
Interfaces and document access
Published module records include UART / TTL and RS-422 options. Interface availability is model specific; confirm logic levels, protocol and connector configuration in the exact record. Use technical downloads and driver resources. Machine-readable discovery is available at llms.txt and llms-full.txt.
Publication boundary
We do not publish unverified numbers as facts. Source disagreements remain identified, and the delivered configuration is confirmed in writing. Catalog records are not live stock, flight-validation or independent certification records. A registered company address does not establish an owned manufacturing facility. Published module laser classes are manufacturer statements for their documented configurations.
Engineering and purchasing questions
How many products are in the public catalog?
As of 22 October 2026, the catalog has 59 records: 28 at 905 nm, one separately identified 940 nm sensor, 18 complete 1535 nm rangefinder modules and 12 erbium-glass laser-source components. A laser source is not a complete ranging module.
Where can I verify the company and request documents?
Use the company page for published company records, technical downloads for model documents and the inquiry form for the delivered configuration. The public sales email is tommy@erdimail.com.
Where can I get a datasheet or serial driver?
Open technical downloads for the exact model, driver resources and the ErdiTech driver repository for supported protocol families. Confirm the module, firmware, connector and logic voltage before using a driver. Documentation availability does not establish flight-controller compatibility.
What are the sample quantity and lead time?
Send your model, quantity, configuration and evaluation requirements. Sample terms, order quantity, pricing and lead time are confirmed in writing. An inquiry does not reserve stock or establish a delivery date.
Request a sample or an engineering review
Send the model or application, target and distance, host interface and quantity. We confirm the delivered configuration, sample terms and lead time in writing. Email tommy@erdimail.com or use the existing inquiry form below.
