VL53L0X with Arduino Mega 2560 R3

Wiring for the VL53L0X time-of-flight distance on the Arduino Mega 2560 R3 (ATmega2560, 5 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	Arduino Mega 2560 R3 pin	Notes
VIN	Power	5V
GND	Ground	GND
SCL	I2C clock (SCL)	SCL 21 (PD0)
SDA	I2C data (SDA)	SDA 20 (PD1)
XSHUT	Input to the part	22 (PA0)	Shutdown, active LOW. Optional; needed to use several sensors
GPIO1	Interrupt	~2 (PE4)	Interrupt output, optional

Check before you power it on

Supply: 5 V from the 5V pin.
I2C uses the board’s default pins SDA 20 (SDA) and SCL 21 (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 = SDA 20, SCL = SCL 21 (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() {}

Questions

Which Arduino Mega 2560 R3 pins do I use for the VL53L0X?

VIN → 5V, GND → GND, SCL → SCL 21 (PD0), SDA → SDA 20 (PD1), XSHUT → 22 (PA0), GPIO1 → ~2 (PE4).

Does the VL53L0X work with the Arduino Mega 2560 R3 at 5 V?

Yes: the VL53L0X runs at 3.3-5 V and the Arduino Mega 2560 R3 uses 5 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.
