VL53L1-SATEL Breakout Boards STMicroelectronics VL53L1-SATEL Breakout Boards are based on the VL53L1 Time-of-Flight (ToF) Proximity Sensor with multi-object detection. The VL53L1-SATEL Breakout Boards are designed to easily integrate the VL53L1 Proximity Sensor into custom applications. The Breakout Boards include a voltage regulator and level shifters, enabling them to be used in any application with a 2.8V to 5.0V supply.
