UM3120 User manual Getting started with the X-NUCLEO-53L8A1 Time-of-Flight expansion board based on the VL53L8 series for STM32 Nucleo Introduction The X-NUCLEO-53L8A1 is an expansion board for any STM32 Nucleo development board equipped with the Arduino R3 connectors. It provides a complete evaluation kit that allows you to learn, evaluate, and develop applications based on the VL53L8 series Time-of-Flight sensors. The expansion board is delivered with a cover glass holder in which you can fit three different spacers of 0.25, 0.5, and 1 mm height below the cover glass to simulate various air gaps. A small oval cover glass fitting the sensor is included. Several ST expansion boards can be stacked through the Arduino connectors, which allow, for example, the development of VL53L8 applications with Bluetooth or Wi-Fi interfaces. Figure 1.

The X-NUCLEO-53L8A1 integrates: • • • Important: the VL53L8 sensor; Arduino UNO R3 connectors; Connectors for SATEL-VL53L8 optional breakout boards; Program a microcontroller to control the VL53L8 through the I2C bus. The application software and an example of the C-ANSI source code are available on the sensor web page. The X-NUCLEO-53L8A1 expansion board can be connected to the STM32 Nucleo development board through the Arduino UNO R3 connectors (CN5, CN6, CN8, and CN9). I²C (up to 1 MHz) and SPI (up to 20 MHz) interfaces are available on the X-NUCLEO-53L8A1 expansion board. The user can choose between the two using the J9 jumper to configure the SPI_I2C_N signal as depicted in the following picture. Figure 5. Use onboard jumper J9 to select between I2C and SPI interfaces UM3120 - Rev 2 page 5/24 UM3120 Breakout boards 3 Breakout boards The X-NUCLEO-53L8A1 package does not include the VL53L8 breakout boards. You can purchase them in a pack of two PCBs as SATEL-VL53L8. For mechanical integration purposes, it could be interesting to use the mini PCB by breaking the SATEL-VL53L8 along the red line as shown in the figure below. It is easier to integrate this setup into a customer's device thanks to its small size. Figure 6. SATEL-VL53L8 The SATEL-VL53L8 boards cannot be directly plugged onto the X-NUCLEO-53L8A1 through the two 6-pin headers (see Figure 7). They can be connected to the X-NUCLEO-53L8A1 by using the mini PCB through flying wires (see Figure 9. VL53L8 mini PCB flying wire connection to the X-NUCLEO-53L8A1 expansion in SPI mode. J9 jumper with pin 1 and 2 connected). The schematic can be duplicated for the sensor on the right allowing the use of both mini PCB. UM3120 - Rev 2 page 6/24 UM3120 Breakout boards Figure 7.

The X-NUCLEO-53L8A1 expansion board requires the NUCLEO-F401RE development board to use the GUI or run the ranging examples included in the X-CUBE-TOF1. Important: Despite the fact that the X-NUCLEO-53L8A1 can be stacked on any STM32 Nucleo board equipped the Arduino R3 connectors, the GUI is designed to work with the NUCLEO-F401RE only. Download the GUI (in the Tools and Software tab of the X-NUCLEO-53L8A1 web page) or the X-CUBE-TOF1 to evaluate the VL53L8.
