This is an Arduino Compatible Interface Shield for interfacing with Blushless DC (BLDC) Motors having their own 3-Phase controllers with a PWM Speed Set Input. It supports either a two-signal 90-deg quadrature speed sensor or a 3-Phase Hall-Effect speed sensor input. It has support for an optical reflectivity sensor for Zero-Position/Index sensing or it can use an external Z-Pos Index Sensor. Supports both 3.3V and 5V logic with on-board level shifters.
