VL53L0X with WeAct Black Pill STM32F411CE

Wiring for the VL53L0X time-of-flight distance on the WeAct Black Pill STM32F411CE (STM32F411CE, 3.3 V logic), chosen with the same pin rules BoardPilot uses: default buses first, and no pins that are used for flash, USB, the debugger or booting.

Wiring

VL53L0X pin	Role	WeAct Black Pill STM32F411CE pin	Notes
VIN	Power	3V3
GND	Ground	G
SCL	I2C clock (SCL)	B6 (PB6)
SDA	I2C data (SDA)	B7 (PB7)
XSHUT	Input to the part	B12 (PB12)	Shutdown, active LOW. Optional; needed to use several sensors
GPIO1	Interrupt	A0 (PA0)	Interrupt output, optional

Check before you power it on

Supply: 3.3 V from the 3V3 pin.
I2C uses the board’s default pins B7 (SDA) and B6 (SCL). Most modules include pull-up resistors; if the part is not found, check them and swap-test SDA/SCL.
To make sure it is the real chip, read register 0xC0: a genuine part answers 0xEE.

Test code (Arduino)

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin();  // SDA = B7, SCL = B6 (the board's default I2C pins)
  Wire.beginTransmission(0x29);
  bool found = Wire.endTransmission() == 0;
  Serial.println(found ? "VL53L0X time-of-flight distance found at 0x29" : "Not found: check power, GND and SDA/SCL");
}

void loop() {}

Arduino board: STMicroelectronics:stm32:GenF4:pnum=BLACKPILL_F411CE,usb=CDCgen,upload_method=dfuMethod. To upload over USB, hold BOOT0, press and release NRST, then release BOOT0 (DFU mode). An ST-LINK on the SWD pins also works.

Questions

Which WeAct Black Pill STM32F411CE pins do I use for the VL53L0X?

VIN → 3V3, GND → G, SCL → B6 (PB6), SDA → B7 (PB7), XSHUT → B12 (PB12), GPIO1 → A0 (PA0).

Does the VL53L0X work with the WeAct Black Pill STM32F411CE at 3.3 V?

Yes: the VL53L0X runs at 3.3-5 V and the WeAct Black Pill STM32F411CE uses 3.3 V signals, so no level shifting is needed.

What is the I2C address of the VL53L0X?

0x29. An I2C scan (BoardPilot does it for you) shows which one your module uses.

BoardPilot checks this wiring in 3D as you build it, and finds crossed or missing wires on the real board.
