LiDAR Library for Arduino

Laser distance scan sensor (LIDAR) Arduino wrapper/controller for kaia.ai home robot software platform. Please check out the Awesome 2D LiDARs list and read this blog post for more details.

Please visit the Support Forum!

This library supports:

• YDLIDAR X4, X4-PRO, X3, X3-PRO, X2/X2L, SCL models
• SLAMTEC RPLIDAR A1
• Neato XV11/Botvac
• Xiaomi Roborock Mi 1st gen LDS02RR
• 3irobotix Delta-2A, Delta-2B, Delta-2G, Delta-2A 115000 baud
  • Note: there is a fixed pattern noise issue that needs debug
• LDROBOT LD14P
• CAMSENSE X1

Other models are in the works.

Connecting to Arduino

Please follow this tutorial to connect LDROBOT LD14P to Arduino ESP32.

Adapter Boards

Some LiDAR/LDS models do not have built-in motor control and therefore require an additional board to operate:

• for Xiaomi Roborock 1st gen LDS02RR use this board
• for Neato XV11 use this board
• for 3irobotix Delta-2A, -2B, -2C PRO, -2D, -2G use this board

ESP32 Modules

• When using the ESP32 WROVER board, it's worth using pins 32 and 33 instead of pins 16 and 17, which are used for QSPI
• When using the YD ESP32-S3, consider the default TX1, RX1 GPIO15 and GPIO16 pins and change the example code to HardwareSerial LidarSerial(1);

Performance Notes

• currently Delta-2A, -2B, -2G exhibit mysterious fixed pattern noise
  • this noise does NOT show when using 3irobotix development kit, so it should be fix-able (somehow)
  • so far I haven't heard back from 3irobotix support.
