Spacers and covers

The 

X-NUCLEO-53L4A1

 expansion board is delivered with:

three spacers of 0.25 mm, 0.5 mm, and 1 mm height, used to simulate different air gaps between the

VL53L4CD

 and the rectangular-shaped cover glass;

an oval-shaped cover glass to simulate the integration of the 

VL53L4CD

 into the customer's final product;

two six-pin headers that allow connecting the two breakout boards to the 

X-NUCLEO-53L4A1

 expansion

board.

Attention:

The 

VL53L4CD

 is delivered with a liner to prevent potential foreign material from piercing the module holes

during the assembly process. Remove this liner before use.
