YDLIDAR (EAI)
YDLIDAR GS2: solid-state linear-array triangulation lidar for robot edge, cliff and obstacle sensing — 25–300 mm at 80 % reflectivity, 100° FoV, 0.6° angular resolution, 7.5–28 Hz, ≤ 3 mm error to 100 mm, 25 klux sunlight, 3.3 V (100 mA), UART 921600 bps on a ZH1.5-4P, 808 / 850 nm Class 1, 25.6 × 23.6 × 10.8 mm, 4.2 g.
GS2Development boardFacts about the complete product. Unknown values remain open design questions.
Guidance to help you shortlist. The basis is shown for each recommendation.
YDLIDAR lists robot obstacle avoidance and vacuum-robot navigation; DFRobot adds wall-following and anti-falling: a 100° line of points at 25–300 mm with ≤ 3 mm error up to 100 mm, no moving parts.
Manufacturer guidanceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
Generated from the datasheet's dimensioned drawing and measured against it. Download the STEP to check fit in your own enclosure.
How far it sees, how fast it scans, and how the robot reads it.

Max range is the printed figure at the stated target reflectivity; accuracy is the typical datasheet value. Scan frequency is the default rotation or frame rate.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
