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, and it is included as part of the Pololu Chassis Kit for TI-RSLK MAX. 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 has extended male headers already soldered in, so it is ready to plug directly into the Chassis Board.
