With the Stepper Brick one bipolar stepper motor with a maximum current of 2.5A and a maximum voltage of 38V 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.
The maximum driving current and the decay mode can also be controlled. The current consumption and power supply voltage can be measured by the API.
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.
