Digilent PowerBRICKS are designed to easily plug directly onto your breadboard for simple, low-profile integration. There are four options to choose from: 12 V, 9 V, 5 V, and 3.3 V. Each is powered by USB and can provide up to 1.1 W of power. In addition, PowerBRICKS can be daisy-chained to provide more than one ± V_OUT pair. (Total power output for the entire chain should not exceed 2.2 W.)
