I am looking for a datasheet or other information on the line following sensor on the XRP Beta.
From the board overview, it looks like the board has no built-in Line following sensor. XRP Controller Overview - SparkFun XRP Controller Hardware Overview
The Line connector is where you’ll plug the cable for the line follower sensor into. This connects the sensor’s two signal lines, Left and Right, to the RP2350’s GPIO44 (Left) and GPIO45 (Right) pins. You’ll use these pins to monitor whenever the sensor detects the robot has gone past the left or right threshold when performing line-following experiments. When connecting the Qwiic adapter cable that plugs into this connector, make the following connections to the Line Follower Sensor:
-
Red - 3.3V
-
Blue - S1
-
Yellow - S2
-
Black - GND
Hi PSWFU.
The line following sensor is just two sensors that detect how much light is reflected off the ground. There’s a datasheet for the sensors on the product page below.
It’s pretty simple in how it works, light colors will reflect more light and dark colors less. The outputs are analog voltages that change based on how much reflected light they sense.
Thanks much. Very helpful.
