最近想做一款廉价版的激光雷达， 刚好前段时间搞定了无刷直流电机的驱动， 就差个激光测距的传感器了， 淘宝一下， 发现ST的VL53L0X卖的比较多， 模块的话， 报价50元， 芯片的话， 40块可以淘宝到， 虽然ST官网报价只有2.3美金:

VL53L0X简介

• 940nm Laser, Eye safe, Time-of-Flight (ToF) laser-ranging module
• Absolute distance provided (in mm) up to 2 meters in less than 30 ms
• Fast mode: quick ranging operation at 50 Hz
• Advanced embedded optical cross-talk compensation to simplify cover glass selection
• I2C interface for device control and data transfer, Xshutdown (Reset) and interrupt GPIO
• block diagram:
  
• schematic:
  
• 3种测距模式: Continuous Timed,Continuous, Single.
• 校准: SPADs, Temperature, Offset, CrossTalk.
• RangeProfiles:
  
• RangingFlow:
  

TARGETED APPLICATIONS

• Camera assist (ultra-fast autofocus and depth map)
• User detection for power saving in smartphones or laptops
• Gesture control
• Drones
• Robotic and industrial control
• IoT
• Domestic appliances
