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.
