Boardoza VL53L7CX-4 Time-of-Flight Breakout Board
The Boardoza VL53L7CX-4 Time-of-Flight Breakout Board is built around the STMicroelectronics VL53L7CX multizone Time-of-Flight (ToF) ranging sensor. The sensor combines a 940 nm invisible VCSEL emitter with a SPAD receiver array to provide accurate distance measurements across a configurable 4×4 or 8×8 ranging matrix, offering up to 64 independent measurement zones. Designed for systems operating from a 3.3 V to 5 V supply rail, the board includes an onboard 3.3 V LDO regulator that provides the required operating voltage for the sensor. In addition to standard I²C communication, the board offers useful control functions, including an interrupt output (INT), communication enable control (LPn), and I²C interface reset (RST). Its dual-connector layout allows multiple boards to be connected in a cascaded configuration, making it easier to operate more than one VL53L7CX board on the same I²C bus. The board is well suited for robotics, occupancy detection, gesture recognition, obstacle avoidance, smart appliances, industrial automation, and other embedded sensing applications.
