URM06 - RS485 Ultrasonic Sensor [Discontinued] Colour_Purple The ring is fully chainable

The ring is fully chainable — simply connect the output pin of one ring to the input pin of the next

It no longer includes a board edge mounting kit for Model B rev 1

that the large screwdriver has a built in ratchet

Continuous rotation servo - rotates fully forward or backward rather than moving to a fixed position

but a breadboard-friendly level shifter is included so you can safely use it with 3V or 5V microcontrollers

URM06 - RS485 Ultrasonic Sensor [Discontinued] Colour_Purple The ring is fully chainableUltrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. They are widely used in detecting displacement, thickness, distance, water level, material level and transparent objects. The URM06 RS485 Ultrasonic sensor provides very short to long range detection and ranging from 20cm ~ 10m, comes in a compact, robust
