Description
The board allows the user to test the VL53L1 functionality, to program it and to understand how to develop an
application using the VL53L1. It integrates:
•
2.8 V regulator to supply the VL53L1
•
Level translators to adapt the I/O level to the main board of the microcontroller
•
Arduino UNO R3 connectors
•
Optional VL53L1 breakout board connectors
•
Solder drops to allow different configurations of the expansion board
It is fundamental to program a microcontroller to control the VL53L1 through the I2C bus. The application software
and an example of the C-ANSI source code are available on www.st.com/VL53L1.
The X-NUCLEO-53L1A2 expansion board and STM32 Nucleo development board are connected through the
Arduino UNO R3 connectors CN5, CN6, CN8, and CN9 as shown in
Figure 3. X-NUCLEO-53L1A2 expansion
and as described in
Table 3. Left Arduino connector
Table 4. Right Arduino connector
The X-NUCLEO-53L1A2 must be plugged onto the STM32 Nucleo development board through the Arduino UNO
R3 connectors.
