The Digital Control Unit Power Output Kit (DCU-POP) is a great starter set of output devices for use with the Digital Control Unit (DCU-BTD). The kit includes several output devices, including a motor, LEDs, incandescent light bulbs, and connecting wires.
Most components will require external power to operate. The DCU is designed to accept LabQuest Power Supply (LQ-PS) and Vernier AC Adapter (IPS) as external power supplies. Third party power supplies must be either 3.3 mm center-positive or 5.5 mm center-negative barrel connectors.
NOTE: When connecting an LED to the DCU, it is important to wire a current-limiting resistor in series with the LED to avoid damaging the LED.
Note that this product is separate form the KidWind Power Output Pack (KW-POP).
