SparkFun has launched a high-accuracy time-of-flight (ToF) short-range proximity and distance sensor primarily based on STMicroelectronics’ VL53L4CD, providing a excessive measurement decision at ranges from 1mm to 1,300mm (round 0.04″ to 51.2″).
“This SparkFun Distance Sensor Breakout makes use of the VL53L4CD subsequent technology ToF (Time of Flight) sensor module,” SparkFun explains of its newest board, “to provide the extremely correct measurements at brief ranges for its measurement.”
Constructed with two Qwiic connectors for solderless set up, although with unpopulated pins out there for anybody who fancies heating up their iron and putting in the breakout onto a breadboard, the compact sensor board affords an accuracy of round ±7mm (round ±0.28″)with a minimal learn distance of 1mm (round 0.04″).

There are a number of little gotchas anybody thinking about putting in the board ought to be aware. The primary is its working voltage of two.6-3.5V; the second is that it is an infrared VCSEL, a Vertical Cavity Floor Emitting Laser, which is a Class 1 laser; and the third is that its I2C deal with is fastened at 0x29, that means anybody wanting to make use of multiple sensor on a single I2C bus will want a multiplexer.
The SparkFun VL53L4CD breakout board is now out there from the corporate retailer, priced at $19.95 earlier than quantity reductions. Anybody who has used the corporate’s longer-range VL53L1X breakout will discover their tasks straight transferable, as famous in the up to date hookup information for each boards.
