LR4 - Precision USB Laser Rangefinder

The LR4 interface board adds a USB port to an off-the-shelf, inexpensive laser distance measurement tool, allowing software to control the rangefinder and automate data collection.

When attached to a simple Fluke 414D laser measurement tool (available Fry's or for around $125), the LR4 forms a USB attached laser rangefinder ideal for industrial or robotics use.
