Problem using I2C with firebeetle 2 esp32 c6

Hi there

I want to connect a VL53L0X via I2c to my new firebeetle 2 esp32 c6. However, I receive the following error: “E (250) i2c.master: I2C transaction unexpected nack detected”

The same code and sensor is working perfectly on a xiao esp32 c6.

I've measured the voltage directly on the firebeetle relativ to ground for sda and scl. All sda/scl pins on the board do not have a voltage.

They should be around 3.3V, right?

Is there something missing on the setup procedure?

```

SFEVL53L1X distanceSensor;

…

void setup(void) {

  Serial.begin(115200);

  Wire.begin(SDA, SCL); 

  if (distanceSensor.begin() != 0) {

    Serial.println("Sensor failed to begin. Please check wiring. Freezing...");

    while (1) delay(10);

  }

  Serial.println("Sensor online!");

  …

}

…

```

thank you in advance
