With the Silent Stepper Brick one bipolar stepper motor with a maximum current of 1.6A and a maximum voltage of 46V per phase can be controlled over USB. With the provided API for many programming languages you can control the direction, velocity and acceleration of the connected motor. Step modes of the motor can be chosen between full-step and 1/256-steps.
Two Bricklet ports can be used to extend the features of this Brick. It can also be used together with other Bricks in a stack. For example an additional Master Brick with Master Extension allows to replace the USB connection by other cable based (RS485, Ethernet) or wireless (WIFI) connections.
The stepper motor can be powered by an external power supply connected directly to the Brick (black connector) or by the stack internal power supply. If an external power supply is connected the Brick automatically switches to this power supply.
It is possible to run the Silent Stepper Brick in a variety of different modes. The stepper motor can be driven completely noiseless (Stealth Mode), with smart energy optimizations (Coolstep Mode) or with maximized torque (Classic mode). The Silent Stepper Brick can be configured to switch between these modes automatically dependent on motor velocity.
A comparison video between Stepper Brick and Silent Stepper Brick is available on Youtube:
The Silent Stepper Brick currently still uses 10-pole Bricklet connectors. You need 10p-7p Bricklet cables to connect Bricklets to it.
