What is it?

The QRD1114 Board allows you to use a QRD1114 Optical Detector easily by adding two resistors (10K ohm and 330 ohm.) We've used these for detecting an object passing over the sensor and we needed an easy way to mount it so I added mounting holes that can use 3mm bolts or #4 screws.

Why did you make it?

Originally created for museum exhibits where the could be easily mounted using screws, these boards have come in handy for consistency versus using perfboard. I've found these boards useful for other projects and thought it might be worth sharing.

You can solder on header pins or screw terminals for breadboard use, or just a set of wires if mounted.

What is not included?

This Board includes only the PCB. It does not include a QRD1114 Optical Detector, resistors, or mounting hardware.
