With the DC Brick you are able to control one DC brushed motor (max. 28V and 5A (peak)) over USB. With the provided API for many programming languages you can control the direction, velocity and acceleration of the connected motor.
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.
Besides methods to control the connected motor the API provide the possibility to measure current consumption or the voltage of the power supply. In case of overtemperature and overcurrent callbacks can be triggered. These can be used to react properly in your own program to these events. For battery driven applications an undervoltage callback is user configurable to prevent damaging batteries caused by depth discharge. Additionally, the drive mode can be switched between Drive/Brake and Drive/Coast (see Drive Modes).
With the power supply connector jack (black) motors can be powered directly. If a stack is used, the connected motors can also be powered through the stack. The Brick switches automatically to the external power supply if connected.
