VL53L1X ToF Sensor Breakout 4-400cm

The Pimoroni VL53L1X breakout is a time-of-flight distance sensor for makers and developers building IoT edge devices. It measures from 4cm to 400cm with a 27° field of view and up to 50Hz ranging frequency. Accuracy is ±25mm, or ±20mm in dark conditions. The board communicates over I2C at address 0x29 and works with 3.3V or 5V logic.

Replaces shorter-range or slower proximity sensors

Upgrade from basic ultrasonic or infrared modules when you need laser-based precision up to four metres and faster sampling. The jump is worth it for robotics, liquid-level monitoring or presence detection where ±25mm accuracy and 50Hz updates matter. Reverse polarity protection adds durability during prototyping.

Check I2C address conflicts and voltage logic

Verify that no other device on your bus uses address 0x29 before connecting. Ensure your controller supports 3.3V or 5V I2C levels to match the breakout. Confirm the 27° field of view suits your mounting position and that the 4cm minimum range covers your closest target.

Soalan tentang produk ini

What physical mounting features does the VL53L1X breakout board include?

The breakout has standard header pins for soldering and mounting holes that align with Raspberry Pi HAT standoff spacing for secure attachment.

How is the sensor connected and what is the common wiring mistake?

Connect VCC to 3.3 V or 5 V, GND to ground, and SDA/SCL to the I2C bus at address 0x29; the frequent error is forgetting pull-up resistors on the data lines.

When should the VL53L1X sensor module be replaced?

Replace the module if ranging accuracy drifts beyond the specified ±25 mm tolerance or if the laser emitter degrades and readings become unreliable.
