New products: 16-channel QTR MD reflectance sensor arrays

QTR-MD-16A Reflectance Sensor Array.

We now have 16-sensor, medium-density (8mm-pitch) versions of our new QTR reflectance sensor arrays. Like the versions already released, these new modules are available in analog and RC configurations and with two different sensor types, resulting in four new products in all:

Unlike the medium-density (MD) arrays we have released previously, which just use the high-density PCBs in partially populated configurations, these new 16-channel modules use PCBs specifically designed for an 8 mm pitch. As a result, these are the first MD versions that allow separate control of the odd and even emitters, which gives you extra options for detecting light reflected at various angles. They have the same board dimensions (125 × 16.5 mm) and mounting hole locations as the high-density (4mm-pitch) 31-channel arrays, but the pinout is different.

Awesome range of reflectance sensors.
Would you consider adding i2c bus capability so we don't need to use so many i/o pins on the micro controller?

Cheers,
Dave
Thanks for the feedback! Making a version of these with a microcontroller on board has been on the to-do list for a while, and I hope to get to it next year (I'm writing this on December 31).
