Deep Dive Teardown of the Huawei 192 Line LiDAR L306 LiDAR Sensor

The L306 debuted as the front LiDAR scanner in the AITO M9 – an all-electric luxury SUV launched under the joint brand of Seres Group and Huawei. Huawei’s new LiDAR is a hybrid solid state with a four-sided rotating prism type. It has a 120° horizontal by 20° vertical field of view with a scan rate of up to 20 Hz. Its maximum detection range is 250 m, or 180 m for objects with 10% reflectivity.
The device uses four light emitting diodes with a wavelength of 905 nm for transmitting and a single-photon avalanche diode (SPAD) sensor with a resolution of 189 by 600 pixels for the receiving path. The position of the rotating mirror prism is controlled by a magnetic position encoder. Compared to the L106, the previous Huawei-made LiDAR TechInsights analyzed, the L306 features a complete internal redesign, while sharing some major integrated circuits with the older device. Mechanical parts are much more expensive than average. Enclosures are made of aluminum (AlSi10MgMn). Optical parts (lenses and filters) are made of glass. The internal assembly elements like the board cover and board interposer are made of stainless steel and they cost around $67 in total.
