This is VL53L0X from ST, a 4.4 x 2.4mm ranging sensor that can measure accurate distance up to 200mm (2 meters). This is a BGA with a I2C interface and have an ST interface library. Several breakout boards exist, but we need to be a bit clever here – I want the sensors mounted in all directions of a robot, so I need more than just a basic breakout board. Being a BGA I hesitate a little, but I think I can mamnage to solder these – if I can afford to buy them that is 🙂
