17.19 RANGING AND GESTURE DETECTION SENSOR EXPANSION BOARD (X-NUCLEO-53L0A1) 437
be connected using the two 10-pin connectors. The basic features of this expansion board are
as follows:

• VL53L0X ranging and gesture detection sensor module.
• Accurate absolute ranging distance, independent of the reflectance of the target.
• Four-digit display, displaying the distance of a target from the ranging sensor.
• Basic gesture recognition application can be developed with a VL53L0X module.
• Cover glass.
• Two VL53L0X satellite boards.
• Two 10-pin connectors for VL53L0X satellite boards.
• Four-digit onboard seven-segment LED display.
This board is described in more detail since a project is given in this section using this
board. The pin layout of this expansion board is shown in Fig. 17.33. The interface between
2
the expansion board and the Nucleo development board is via I C.
