Overview
The X-NUCLEO-53L0A1 expansion board features the VL53L0X ranging and gesture recognition sensor, based on ST’s FlightSense™, Time-of-Flight technology. It is compatible with the STM32 Nucleo board family, and with the Arduino UNO R3 connector layout.
Several ST expansion boards can be superposed through the Arduino connectors, which allows, for example, to develop VL53L0X applications with Bluetooth or Wi-Fi interface.

The X-NUCLEO-53L0A1 expansion board is delivered with:
• Three spacers of 0.25, 0.5 and 1 mm height, used to simulate different airgap between the VL53L0X and the cover glass
• A cover glass to simulate the integration of the VL53L0X into the customer’s final product.
• Two VL53L0X satellites, which can be plugged onto the X-NUCLEO-53L0A1 expansion board or connected through flying wires to the X-NUCLEO-53L0A1 expansion board.
• Two 10 pin connectors to enable customer to connect the two satellites onto the X-NUCLEO-53L0A1 expansion board.
