With the success of the RS7 encoder for the 775pro motor, we have duplicated the design for the AndyMark 9015 Motor (am-0912). The RS5 uses the same mounting, board, and strain relief as the previous design, just a bit smaller to fit the 550 series motor. On the website we added a drop down menu to select the different versions. Also added a datasheet for the sensor IC and an installation instructions. Keep in mind that these are not generic designs and are not tested on the Banebots 550 and 775 motors.
[strike]I think[/strike] The AndyMark 9015 really is part number [strike]AM-9012[/strike] AM-0912. The 9015 designation is historical; there was a Fisher-Price motor marked 9015 included in the KoP, back in the day. That motor was popular because of its peak power.
