VL53L3CX-SATEL Breakout Board STMicroelectronics VL53L3CX-SATEL Breakout Board is used for easy integration into devices. The PCB section supporting the VL53L5CX module is perforated to break off the mini PCB for use in a 3.3V supply application using flying wires. This makes it easier to integrate the VL53L5CX-SATEL breakout boards into development and evaluation devices.
