We have you covered whether you are supporting fully digital systems or mechanical systems communicating with the digital world. Thomas Regional are part of Thomasnet.com. Fortunately my motor mounts are 6+" above the base. it seems like it should be possible to use two sensors to get the quadrature benefit, but it seems like it's going to be too difficult for me to get them precisely mounted well enough for it to work correctly. But according to the Redbot kit, the motors for the same part have a shaft extending about 1 cm (just a guess from the picture). (Answered my own question: The outputs are open-drain, so all the clean-up needed is a pull-up resistor.). The magnetic heads are small enough that they can be placed next to each other, with careful spacing, to create a quadrature encoder to increase resolution and gain direction information. Be sure to keep absolute encoders on hand to support stable systems and incremental encoder wheels on hand to support responsive, rapid-change systems.
