ERDI TECH LTD (Chengdu) manufactures 905 nm and 1535 nm laser rangefinder modules for OEM integration. We publish the unit price, the test condition behind each stated range, the datasheet and the STEP file for every one of our 59 catalog models, and shipping is included on every order. If you integrate sensors into drones, robots or survey equipment, or you sell to people who do, this page explains how a partnership works.
Who this is for
- Drone, gimbal and robotics integrators who buy ranging modules every quarter and want a clear volume price.
- Regional resellers and distributors in Europe, North America, India, Southeast Asia and the Middle East.
- University labs, makerspaces and training programs that need evaluation hardware.
Why partner with ERDI
Public unit prices
All 59 models show a unit price and a volume price table on the model page. Your customers can check the number before they talk to you, so you spend less time on quote rounds.
Shipping included
Every order ships with shipping included, samples too. The price you see is the price you pay.
Open drivers and docs
UART protocol documents and Python and ROS 2 drivers are public. Your customers do not need an NDA to wire a module.
Ranges with conditions
Each stated range comes with its target size, reflectance and visibility, so what you promise your customer is what the datasheet supports.
Laser safety documented per model
Relevant models state IEC 60825-1 Class 1 in the manufacturer datasheet. This is a per-model manufacturer statement, so check the model page for the exact wording.
Evaluation units
Partners can order evaluation units to qualify a model with a real customer before committing to volume. Sample terms are confirmed in the written quotation.
Three ways to work with us
| Program | Who | Terms |
|---|---|---|

Partner tiers
Partner pricing is the volume pricing already published on each model page. There is no extra discount on top of it. For each model, the unit price is the published price band that matches your cumulative purchases of that model over the 12 months of the agreement.
