For an OEM or ODM laser rangefinder module project in China, start with a written measurement and host-interface brief. ERDILRF is the product and inquiry website of ERDI TECH LTD in Chengdu. Compare documented modules first; confirm customization scope, drawings, acceptance criteria, commercial terms and delivery requirements in the quotation.
Start from a documented module
| Model / wavelength | Published range and conditions | Module mass | Serial interface | Supply | Published power |
|---|---|---|---|---|---|
| SPD1200N2 905 nm |
0.2–1,200 m; target and ambient conditions require confirmation | ≤ 5 g | UART-TTL | 3.3–5 V | Average ≈ 0.45 W · max ≤ 0.75 W |
| LRF3000A1 905 nm |
≥ 3,000 m @ 70% reflectivity, building target (clear weather, visibility ≥ 4 km) | 12 ± 0.5 g | UART (TTL 3.3 V) | DC 3.3–5 V | ≤1.8 W at +25 °C; check peak demand separately |
| LRF0306C 1535 nm |
≥ 4000m @60% Reflectivity, Building Target ≥3000m @30% Reflectivity, 2.3×2.3m Target ≥1500m @30% Reflectivity, 0.5×1.7m Target ≥800m @30% Reflectivity, 0.2×0.3m Target; visibility >8 km for these source test cases | ≤14 ±1 g (notation as printed in the module document) | UART(TTL 3.3V) | DC 3~5V | 5 V: ≤0.9 W at 1 Hz; <1.1 W at 3 Hz; peak ≤3W |
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.
Turn a requirement into an evaluation plan
- Measurement brief: target, distance, reflectivity, environment, acceptable error and valid-output timing.
- Interface and drawing review: supply, logic voltage, connector, protocol, optical window and mechanical envelope.
- Sample definition: exact model, configuration, document revision and the tests your host will perform.
- Acceptance: agree the measurement conditions, inspection record and pass criteria in writing. Ask which assembly, alignment and calibration records accompany the proposed unit.
- Commercial confirmation: confirm customization scope, quantity, sample terms, lead time, duties and taxes in the quotation.
Company identity and manufacturing evidence
Use the company facts card and company records to check the legal entity and registered address. A registered address is not evidence of an owned machining plant. Request project-specific process and acceptance documentation when your supplier review requires it. We do not publish unsupported production-capacity or certification numbers.
For supplier background, use the existing manufacturer information page. For technical tradeoffs, compare 905 nm and 1535 nm modules.
Engineering and purchasing questions
Where is the company based?
ERDI TECH LTD is registered in Chengdu, Sichuan, China. ERDILRF is its product and inquiry website. The facts card lists the registered address and Unified Social Credit Code, with links to the existing company records.
Which OEM / ODM changes can I order?
Send the exact module and requested mechanical, electrical, protocol or firmware changes. The review determines feasibility, required documents, sample configuration and acceptance criteria. Only a written quotation confirms the agreed scope.
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.
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.
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.
