Si72xx-WD-KIT Magnetic Sensor Wheel Demo Kit

The SI72xx-WD-KIT showcases the performance and versatility of the Si72xx platform. The wheel demo board shows degree-accurate position sensing, along with low power quadrant detection and revolution counting. 6 postage-stamp daughter boards allow you to evaluate the full range of Si72xx parts in conjunction with the rest of the kit. The postage stamp boards are also designed to be easy to connect to externally and prototype with for maximal flexibility.
