360° Radar Module with STM32 Chip

Lidar is one of the modern remote sensing methods that detects and measures distances by projecting laser beams onto a target. The 360° Radar Module utilizes an STM32 Chip for processing. The radar’s rotation and internal circuits are powered wirelessly, and data transmission is achieved through infrared beams to prevent wear on the primary slip ring. This Radar Module closely resembles the EA1 X2 model. The radar interface also outputs data directly via a serial port.

The maximum measurement frequency of this Radar and Laser Scanner reaches 4000 points per second, with a baud rate of 115200. Additionally, the radar supports PWM speed adjustment for scanning frequency control and interface definition. The wiring sequence—VCC, TXD, GND, RXD—starts near the motor.

Applications of the STM32 laser scanner

1. Robot SLAM positioning and obstacle avoidance
2. Surveying and mapping
3. ROS-based robot development
4. Interactive gaming
