VL53L5CX 8x8 multizone time-of-flight with ESP32

Supply 3.3 V Bus I2C I2C address 0x29 Measures distance

Pins and ESP32 wiring

Pin	Role	ESP32 pin	Notes
INT	Interrupt	D35	Data ready, optional. SATEL-style order; other boards differ
I2C_RST	Not wired to the ESP32	—	I2C reset, active HIGH. Tie to GND
SDA	I2C data (SDA)	D21
SCL	I2C clock (SCL)	D22
LPN	Input (the ESP32 drives it)	D25	Low-power enable: HIGH to talk over I2C. Can be tied to IOVDD
PWREN	Not wired to the ESP32	—	Enables the on-board regulator. Tie to IOVDD
AVDD	Power	3V3	Use 3V3
IOVDD	Power	3V3	Use 3V3
GND	Ground	GND

Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.

Starter code (Arduino)

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin(21, 22);  // SDA = GPIO 21, SCL = GPIO 22
  Wire.beginTransmission(0x29);
  bool found = Wire.endTransmission() == 0;
  Serial.println(found ? "VL53L5CX 8x8 multizone time-of-flight found at 0x29" : "Not found: check power, GND and SDA/SCL");
}

void loop() {}
