Description

1 axis stepper motor controller board

The SSM1ST2420HC is an one axis small form factor Motion Controller Module and 2-phase bipolar stepper motor with a high torque and has sophisticated features like an ultra low-noise chopper mode, a way to drive the motor with very high efficiency, and a programmable stall guard. The SSM1ST2420HC can be controlled and configured by the onboard STM32-Cortex M0x microcontroller. On the back of the PCB a Hall sensor is placed to allow for a closed loop system without the need for an encoder. If an encoder is preferred, this can also be used and connected to the encoder connector on the PCB. To allow for versatile use cases , the SSM1ST2420HC board features a CAN bus with 2 connectors making the board suitable for “daisy chaining”, Further it offers 2 isolated 24V tolerant Inputs, outputs and 1 analog port for connecting external electronics.
