Can it switch a relay or small DC motor?
Its 4 A rating allows switching moderate loads, but check the coil or motor current and use a flyback diode for inductive loads. Confirm the base drive requirements in the datasheet.
Can a microcontroller pin drive its base directly?
Usually not for full switching. The base needs enough current to saturate the transistor, so a small driver transistor or a resistor calculated from the datasheet gain is typically used.
