AM305122R1DBGEVB: Daughter Board SPI Stepper Driver Voltage Regulator SOIC Evaluation Board


The AM305122R1DBGEVB is a form factor Daughter Board for driving bipolar stepper motors. The daughter board can be interfaced via I/O pins and the SPI bus to an external microcontroller. In conjunction with the evaluation kit AMIS305XXGEVK it forms a complete solution turning high level commands from a CAN node in well defined motions. The design incorporates the lowest bill of materials, small board size and perfect matched thermal resistance allowing to drive 400 mA at elevated ambient temperature or even 800mA under certain conditions.

Note: This board must be used with the AMIS305XXGEVK Industrial Stepper Motor Driver Kit.
