TFmini-S LiDAR Module

TFmini VS TFmini-S

TFmini-S is a single-point ranging Lidar based on TFmini upgrade. The blind zone of it is reduced from 30cm to 10cm, the outdoor ranging performance is further improved, the distance range is not disturbed by ambient light, which can be consistent with the indoor range, and the accuracy is further optimized. The error performance at 10% reflectivity approaches the background of 90% reflectivity, and the interface supports UART and I2C switching at any time.
