VL53L0X with Teensy 4.1

Wiring for the VL53L0X time-of-flight distance on the Teensy 4.1 (MIMXRT1062DVJ6B, 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	Teensy 4.1 pin	Notes
VIN	Power	3V
GND	Ground	G
SCL	I2C clock (SCL)	19 (GPIO_AD_B1_00)
SDA	I2C data (SDA)	18 (GPIO_AD_B1_01)
XSHUT	Input to the part	2 (GPIO_EMC_04)	Shutdown, active LOW. Optional; needed to use several sensors
GPIO1	Interrupt	3 (GPIO_EMC_05)	Interrupt output, optional

Check before you power it on

Supply: 3.3 V from the 3V pin.
I2C uses the board’s default pins 18 (SDA) and 19 (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 = 18, SCL = 19 (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: teensy:avr:teensy41. Press the white program button once if the upload waits for the board.

Questions

Which Teensy 4.1 pins do I use for the VL53L0X?

VIN → 3V, GND → G, SCL → 19 (GPIO_AD_B1_00), SDA → 18 (GPIO_AD_B1_01), XSHUT → 2 (GPIO_EMC_04), GPIO1 → 3 (GPIO_EMC_05).

Does the VL53L0X work with the Teensy 4.1 at 3.3 V?

Yes: the VL53L0X runs at 3.3-5 V and the Teensy 4.1 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.
