Boardoza VL53L7CX-1 Time-of-Flight Breakout Board
The Boardoza VL53L7CX-1 Time-of-Flight Breakout Board is a compact ranging sensor board built around the STMicroelectronics VL53L7CX multizone Time-of-Flight (ToF) sensor. Designed for embedded systems operating entirely at 3.3V supply and logic levels, it provides accurate distance measurements with an ultra-wide 90° diagonal field of view using a configurable 4×4 or 8×8 ranging zone matrix.
With its advanced 4×4 or 8×8 multizone ranging capability, ultra-wide 90° diagonal field of view, and support for communication and control functions such as interrupt-based operation, communication enable control, and I²C interface reset (INT, LPn and RST), the board is ideal for robotics, obstacle detection, occupancy sensing, gesture recognition, smart appliances, industrial automation, and other embedded applications where accurate distance measurement and compact size are important. Its dual-connector layout also allows multiple boards to be connected in a cascade connection, making it easier to use more than one VL53L7CX board on the same I²C bus.
