AM306245R2MMGEVB: Motor Module I²C Stepper Driver NQFP Evaluation Board

The AM306245R2MMGEVB Motor Module holds a stepper motor driver IC with position controller and control/diagnostics interface integrated on one small PCB. This is available in a size to fit on a NEMA16 stepper motor.
The Motor Module receives high level positioning instructions through the I²C interface and subsequently drives the motor until the desired position is reached. This high abstraction level of commands reduces the load of the processor on the master side.
The position controller is configurable for different motor types, positioning ranges and parameters for speed, acceleration, deceleration, hold current, safe position. Six OTP bytes are available to set default values, and can be overruled by values programmed through the I²C bus. The Motor Module can be programmed to detect and act on mechanical blocking of the rotor.
The AM306245R2MMGEVB Motor Module acts as a slave on the serial bus and the master can fetch specific status information like actual position, error flags, etc. from each individual slave node.

Note: This board must be used with the AMIS3062XGEVK Industrial Stepper Motor Driver Kit.
