Pololu 8-Channel QTRX Sensor Array for Romi/TI-RSLK MAX (Headers Not Soldered)

This reflectance sensor module is designed specifically for use with Romi or TI-RSLK MAX robots based on the TI-RSLK Chassis Board v1.0. It features eight IR LED/phototransistor pairs that are great for identifying changes in reflectance on the ground underneath the robot (like detecting or following a black line on a white background). The sensor array offers dimmable brightness control with separate controls for the odd and even emitters, and each sensor provides an independent output that can be measured with a digital I/O. This version includes extended male header pins, but they are not soldered, so soldering is required to use this product.
