Genuine Liancheng JC02-1 Laser Rangefinder Module 600-1200m for FPV Drones and ArduPilot

Description

Genuine Liancheng JC02-1 Laser Rangefinder, Direct from the Manufacturer

This is the genuine Liancheng JC02-1 laser distance measuring module, supplied direct from the manufacturer, Liancheng Electronics Co., Ltd., not a clone or rebrand. We stock the genuine module because it is the one we use ourselves: the JC02-1 is the rangefinder fitted in our MTS Rangefinder PTZ head, dimensioned around its 12.8 x 25.05 x 27.56 mm body.

The JC02-1 is a compact pulsed laser distance sensor for FPV drones, fixed-wing aircraft, ArduPilot / PX4 builds, and DIY robotics. It measures distance over UART serial and connects directly to an ArduPilot flight controller serial port.

Demo code and setup help

Request demo code from us and we will provide you with a testing GitHub repo with test code, wiring diagrams, and setup instructions. Contact us after your order and we will send you the repo with ESP32 and RP2040 test code, wiring diagrams, and a step-by-step setup guide so you can get ranging data on your first day.

The manufacturer’s documentation repo (Liancheng’s own repo, not ours) is at github.com/liancity2025/JC02-1-Laser-Ranging-Module.

Please note

• This is a secondary-development module: basic programming and serial debugging are required to use it.
• Note the 2.85 V signal level. Level shifting is needed from 5 V / 3.3 V logic.
• The reset command executes silently (no response packet); verify with a single-measurement command after a 500 ms wait.
