STEVAL-VL53L9

The developer can use the STEVAL-VL53L9 along with the camera flex connector, which enables MIPI-based readings and allows interfacing with NUCLEO-N657X0-Q and STM32N6570-DK, Raspberry Pi, and Rockchip platforms.

We can also connect via flying wires on the header. This makes it easier to integrate the board into the development and evaluation devices, thanks to their small size.

The STEVAL-VL53L9 board integrates the VL53L9CX.

The VL53L9CX is a dToF 3D LiDAR all-in-one module, offering a high spatial resolution of 2.3 K zones. It features a 71° diagonal FoV, with 1° angular resolution across a 55 x 42° FoV. It also delivers accurate ranging from 5 cm to 9 m.

The STEVAL-VL53L9 includes one board, which can be easily integrated into the customer devices.
